Transformer™112/212

Modeling Amplifiers

Congratulations on your purchase of the world’s most technologically advanced guitar amp, the Transformer

™

by Peavey. Though instrument amplifier emulation has been occurring for some time now, none have accomplished what Peavey has in the Transformer. Within a small, light weight combo package, Peavey has managed to emulate both the voicing and dampening characteristics of some of the world’s most popular amplifiers using TransTube®Technology.

This guide covers both the Transformer 112 and the Transformer 212. The difference in the two models are noted where applicable. It is important that you read this guide in its entirety. There are extra functions within the Transformer that are not made apparent by the front panel labeling. Just like a computer may have “hot key” combinations (pressing two keys will perform a distinct function), the Transformer uses certain button and knob combinations to achieve special functions. These are explained in detail within this guide. A chart indicating these “hot key” combinations is included for quick reference and a complete section, Transformer Tricks, has been dedicated to the subject.

The Features list and Quick Start section will familiarize you with the Transformer . We’re confident that you will be amazed at the great sound of this amp; however, please read the manual in its entirety. Doing so will give you the knowledge you need to mold and shape your tone and create voicings reminiscent of classic amp designs as well as modern icons. Let’s get started!

QUICK START

This section will allow you to preview the Transformer’s sound capability with hands-on play time.

Caution: Please look over this guide and read any caution or warning statements found within. Following these warnings is crucial to your personal safety and the safety of your Peavey product.

(1) Once you unpack your Transformer , plug the power cord into a socket supplying the

proper AC line voltage for your unit. This is noted on the rear of the unit, near the power switch.

(2) Turn the Master Level control to the “0” position.

ENGLISH

(3) Connect the footswitch (included) to the Footswitch jack in the rear of the Transformer using

the eight-pin DIN cable (included).

(4) Plug your guitar (instrument) into the High Gain input using a high quality shielded instrument

cable.

(5) Flip the power switch to the “ON” position to turn the unit on. This is also a good time to

reinitialize the unit. Turn the unit on while pressing and holding down both the STORE and USER buttons simultaneously. This will reinitialize (or reset) the unit, deleting any alterations to the internal programming that may have occured at the Peavey dealership.

(6) Turn your guitar volume up to your normal playing position or the full volume position,

whichever you prefer.

(7) Gradually increase the Master Level control by turning it clockwise. Do this slowly to avoid

any sudden level changes that could damage your hearing. We recommend setting the amp to a low volume while you are sampling the various presets. As you change from preset to preset using the footswitch, volume changes may occur.

(8) If you wish, you may leave the footswitch disconnected and select the various presets and

banks by hand. This can be done by rotating the Preset Matrix knob on the front of your Transformer to the desired preset location.

After reinitialization, the Transformer will power up in the A1 (first preset) factory preset position. The footswitch comes up “Preset Mode”. Pushing the footswitch buttons labeled 1, 2, 3 and 4 (also labeled A, B, C and D respectively) will select one of the four presets in the A bank. To change from the A bank to the B, C or D banks, push the button marked BANK and enter “Bank Mode”. A yellow Bank LED will blink indicating the current bank. In this mode the same preset buttons (1 - 4) now take on a new meaning. As they are marked, they now select from the banks A-D. Once the desired bank has been selected (by pushing one of the A-D buttons) the footswitch returns to the “Preset Mode”. If this seems confusing refer to the remainder of this guide for a detailed map and explanation of preset structure within the Transformer.

You should now be able to dance around the footswitch selecting the various presets and banks. Once again, it is imperative that you read the remainder of this guide in order to realize all of the functions of the Transformer. This guide is packed with many important cautions as well as visual aids to help you master this feature packed amplifier.

TRANSFORMER 112 PRESET STRUCTURE

This section will describe the overall preset structure of your amplifier. Refer to the diagrams to better understand how the presets are divided and selected on the Transformer .

First, your Transformer is shipped with 16 factory presets and 16 user presets. From Peavey, the 16 factory presets are identical to the 16 user presets (unless manually changed).

Factory Presets

The 16 factory presets are included to give you a good starting point and to illustrate some of the Transformer’s capabilities. Most users will learn from the factory presets and apply what they have learned to the programmable, user presets. When a factory preset is altered it can be stored to a user preset. Any change in a factory setting will be lost (if not stored as a user preset) when the next preset is selected.

User Presets

The 16 user presets come from Peavey loaded with the same presets found in the 16 factory presets. They can easily be “transformed” to your preference and/or saved in the same (or a different) location. It is easy to select between the user and factory presets. Simply press (and quickly release) the User Switch on the front panel of your Transformer to toggle between both. The LED next to the switch will illuminate to indicate you are in the user preset group.

The factory and user presets are each divided into 4 banks (A, B, C and D). Each bank is divided into four individual presets. Therefore, [4 banks] x [4 presets] = 16 (or A1 thru D4). This is demonstrated in the diagram below.

Each preset, factory or user, has primary and secondary settings for gain/EQ, modulation, delay and reverb. These primary and secondary settings do not include amp model, modulation type or delay tempo changes. You can access and edit these settings by placing the PFC 4 footswitch in the EFX Select Mode. That’s a multitude of effects/gain combinations. EFX Select Mode is discussed in detail on page 13.

Important!

Now that you have a good understanding of the preset structure it is important that you keep three things in mind while editing and saving presets.

First, you can change any preset (user or factory) and save it to any of the 16 USER preset locations. For example, you may change the Pre Gain level on factory preset A1 and save it to user preset B3. Of course, when you pull up factory preset A1 the Pre Gain value will revert back to its original value and the new value will be stored in the user preset B3. Once changed, the original user settings will no longer be identical to the factory settings.

Second, whenever you reinitialize the Transformer you perform a hard reset. All programmed presets will be deleted and the Transformer will revert back to its original factory and user settings.

Third, every preset has primary and secondary settings accessible by the EFX Select footswitch mode.

POWER

There are two features that deal with AC power on the Transformer. Both are located on the left, rear panel of the unit. Next to these features you will find the proper AC line voltage requirement for your particular amplifier. It is important that this requirement be met for your unit’s safe and proper use. Refer to the diagram below for the location of these parts.

REAR PANEL

1. REMOVABLE AC POWER CORD (UNDERSIDE OF REAR CHASSIS)

This receptacle is for the IEC line cord (included), which provides AC power to the unit. Connect the line cord to this connector and to a properly grounded AC supply. Damage to the equipment may occur if an improper line voltage is used. (See voltage marking on unit.) Never remove or cut the ground pin of the line cord plug. This unit is supplied with a properly rated line cord. When lost or damaged, replace this cord with one of the proper ratings.

2. POWER SWITCH

Place this switch in the “ON” position to turn the Transformer on. The LEDs on the front panel and the footswitch (if connected) will illuminate indicating that the unit is on.

FRONT PANEL

The front panel of the Transformer features all of the user controls necessary to create the sound and response you want. The footswitch, though also a controlling factor, contains only a small portion of the front panel features. The following section describes the front panel features in detail. Where applicable, features associated with the footswitch are noted. When you complete this section you should know the function of each and every knob and jack on the front panel.

INPUT

3. HIGH GAIN INPUT JACK

This is the standard input used for most instrument applications. Most electric guitars will work ideally when plugged into this 1/4" mono input. The High Gain Input is 6 dB louder than the Low Gain Input (4).

4. LOW GAIN INPUT JACK

This 1/4" mono input is provided for instruments with extremely high outputs, which can result in overdriving (distorting) the High Gain Input (3). If both the Low Gain and High Gain inputs are used simultaneously, their levels are both Low Gain.

PRESET

5. PRESET MATRIX SELECTOR

This encoder switch provides a means of selecting the active preset. Based on the position of the User Switch (6), the encoder switch can select any preset, user or factory. The matrix is divided into four groups (A, B, C and D) representing the four banks. Positions 1 - 4 and their respective LEDs are labeled in each bank to allow for distinct preset selection. The current active preset is always indicated by the illuminated LED next to its position except when storing. During the Store function the blinking LED shows the destination preset and not the current one. The function of the Preset Matrix Selector can also be performed by the footswitch and MIDI program change commands. Refer to the MIDI/Footswitch section of this guide for an explanation of these functions. For a description of the Transformer preset structure go to page 28.

6. USER SWITCH/LED

The User Switch toggles the Transformer between factory presets and user presets. This function can only be performed on the front panel, not the footswitch. The LED next to the User Switch will illuminate when the user presets are active and the factory presets have been defeated.

7. STORE SWITCH

This switch is used to store presets in specific locations. This may be required after a preset has been altered and/or a new preset location is desired. When a preset is finalized and ready for storage, press this switch once. The active matrix LED will begin to flash indicating the current active preset location. If you desire to keep the new preset stored in its current location, press the Store Switch a second time and the operation is complete. However, if you wish to change the preset location, turn the Preset Matrix Selector to the desired new location. When the flashing LED is in the desired location press the Store Switch again and the preset will be saved in its new spot. This function is only available with the Store Switch.

AMP

MODEL

8. AMP MODEL SELECTOR

Use this switch to select the amp you wish to emulate. The LEDs surrounding this switch always reflect the active model for the current selected preset. The amp model can be changed at any time by just rotating the selector switch to the desired amp position. If you decide to store the new amp model in the current preset location, simply hit the Store Switch (7) twice.

The following chart describes the various amp model positions and their characteristics:

9. PRE GAIN

The Pre Gain control sets the input level to the Transformer. Adjusting this control fully clockwise will result in maximum gain. This control is often used to adjust the amount of distortion present in the signal since it can raise the input level to an overdriven state. When using the footswitch in EFX Select Mode, the Pre Gain can be toggled between two settings by pushing the Boost Footswitch (27).

10. EQUALIZATION

The three-band EQ found on the Transformer “transforms” in conjunction with the position of the Amp Model Selector (8). This is understandable when you consider that all amps have different EQ circuitry in them. Some have active EQ and some have passive EQ. Some mid EQ’s have a center frequency of 1 kHz and others may be lower or higher. The Transformer emulates the EQ and even the EQ pot tapers for the particular amp it is modeling. Simply put, adjusting the EQ on the Transformer is comparable to adjusting the EQ on the amp you are emulating. This aids the Transformer in a successful reproduction of the amplifier you desire. Refer to the Amp Model Chart on page 8 for a description of the EQ characteristics of each amp model. When using the footswitch in EFX Select Mode, the EQ settings can be toggled between two settings by pushing the Boost Footswitch (27).

11. POST GAIN

The Post Gain sets the overall volume level for an individual preset. When using the footswitch in EFX Select Mode, the Post Gain can be toggled between two settings by pushing the Boost Footswitch (27). This is a useful function when a sudden change in level is desired within the same preset. Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

The Post Gain should not be confused with the Master Level (19) control which sets the overall volume level of the Transformer as a unit. The Master Level affects all presets and the Post Gain only affects individual presets.

12. MODELING REVERB

This control determines the amount of reverb present in the overall signal. The reverb utilized by the Transformer alters its tone in relation to the Amp Model Selector (8) position. When using the footswitch in EFX Select Mode, the Reverb can be toggled between two settings by pushing the Reverb Footswitch (30). Those two settings can represent any position on the knob, including off (fully counterclockwise). Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

MODULA

TION

13. MODULATION SWITCH

The Modulation Switch selects which type of modulation effect is active. You may select between Chorus, Flanger, Phaser, Tremolo and Rotary Speaker. This function is not available from the footswitch.

14. RATE

The Rate control determines the sweep rate of the modulation effect that is selected by the Modulation Switch (13). Rotating this control clockwise will result in an increased rate. The Rate and Depth (15) settings work together to determine the overall modulation effect. When using the footswitch in EFX Select Mode, the Rate can be toggled between two settings by pushing the Modulation Footswitch (28). Those two settings can represent any position on the knob. Keep in mind, both the Rate and Depth (15) are toggled simultaneously. Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

15. DEPTH

The Depth control determines the sweep depth of the modulation effect that is selected by the Modulation Switch (13). Place this control in the full counter-clockwise position to turn the delay effect off. Rotating this controlclockwise will result in an increased depth and/or mix.

The Rate (14) and Depth settings work together to determine the overall modulation effect. When using the footswitch in EFX Select Mode, the Depth can be toggled between two settings by pushing the Modulation Footswitch (28). Those two settings can represent any position on the knob, including off. Keep in mind, both the Rate (14) and Depth are toggled simultaneously. Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

DELA

16. TAP TEMPO BUTTON/LED

The Tap Tempo button sets the delay time to match that of a certain tempo. Pressing the button several times (at least two) in unison with the desired tempo will reset the delay tempo. A Tempo LED is located next to the Tap Tempo Button to provide a visual representation of the delay rate. This function can also be performed on the footswitch by tapping the Tap Tempo Footswitch while in the EFX Select Mode. Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

NOTE: You can use the two tap switches (footswitch and front panel) together alternating between foot and hand to get very short delay times. Pressing the two almost simultaneously will produce this effect.

17. FEEDBACK

This control determines the number of repeats or the “decay time” for the delayed signal. Turn the knob clockwise to increase the feedback setting. When using the footswitch in EFX Select Mode, the Feedback can be toggled between two settings by pushing the Delay Footswitch . Those two settings can represent any position on the knob. Keep in mind, both the Level and the Feedback are toggled simultaneously. Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

18. LEVEL

This control determines the relative volume of the delayed signal. Turn the knob clockwise to increase the amount of delayed signal found in your overall sound. Place this control in the full counterclockwise position to turn the delay effect off. When using the footswitch in EFX Select Mode, the Level can be toggled between two settings by pushing the Delay Footswitch. Those two settings can represent any position on the knob, including off. Keep in mind, both the Level and the Feedback are toggled simultaneously. Refer to the MIDI/ Footswitch section and the Application Notes for more information on this feature.

MASTER

19. LEVEL

Use this control to adjust the overall (global) gain of the Transformer. This control setting is not linked in any way to a stored preset. Adjust the Level control to various playing situations such as different room sizes or whenever an overall level change is desired. Changes in this control setting will bring up or down all preset levels proportionally. It will not affect the volume of the effects loop.

20. POWER DYNAMICS

This is the famous Peavey T.Dynamics found throughout the award winning TransTube Series amplifier line. The Power Dynamics control adjusts the power level of the amplifier from 10 percent to 100 percent power. When set to lower settings, the power compression simulation will be much more pronounced.

TRANSFORMER 112

TRANSFORMER 212

EFX

21. SEND/RETURN

This pair of 1/4" jacks supplies an effects SEND and RETURN path for the preamp signal. Connect the SEND jack to the input of external, low-level, signal processing equipment (effects). The SEND jack is a stereo (TRS) jack allowing connection to stereo outboard effects as well as a second combo amp like the Transformer. Return the signal from your external equipment to the RETURN jack. This is known as an Effects Loop since the signal exits your amp (send) and loops (return) back to it. When using external effects in stereo you may wish to return the left signal back to the RETURN jack and send the right signal to an additional outboard amplifier or a second Transformer . The TRS SEND jack is wired with the tip as the left signal (which goes to the speaker) and the ring as the right signal. When a mono plug (standard guitar cable) is partially inserted to the first click of this jack, it can be linked to the input of an auxillary amp to achieve stereo sound. Refer to the Recommended Hookup Diagram on page 12 for more info on using this feature. Also see page 22 to find out how to switch the outputs to stereo mode.

HEADPHONE

22. HEADPHONE JACK

This stereo 1/4" jack accepts a standard pair of headphones. Using this jack defeats the output to the speaker making it ideal for quiet practice applications. Although the signal is sent through a stereo connector, the signal is mono and the sound heard in the left earpiece will be a duplicate of that heard in the right.

MIDI

23. MIDI IN/FOOTSWITCH

The MIDI In eight-pin DIN is used to receive MIDI commands from an external MIDI device or controller. The eight-pin DIN connector will accept both five-pin standard MIDI cables as well as Peavey’s eight-pin MIDI/Communication combo cable. By using the eight-pin cable, this DIN connector provides the connection and power for the PFC 4 footswitch (supplied). Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

MIDI/FOOTSWITCH SECTION

The PFC™4 Professional Footswitch included with the Transformer 112 is state of the art. Because the PFC 4 has variety of easy to use functions, the user has access to bank and preset selection, individual effects manipulation, tuner and gain boost. The following section describes each feature of the footswitch as well as a short Transformer 112 MIDI primer.

The PFC 4 operates in four different modes: Tuner Mode, Preset Mode, Bank Select Mode and EFX Select Mode. When the Transformer 112 is first powered up the PFC 4 selects the Preset Mode by default. The numerous buttons on the PFC 4 perform different functions based on the current mode. The current mode is dependent on the condition of the EFX Select Mode Button (25) and the Bank Mode/Tap Tempo Button (26). Therefore, the following section will display the different modes and a description of how each button of the footswitch functions in that mode. If a particular button is not listed under a mode then that button is not applicable. The Tuner Mode does not affect the various functions of the PFC 4. It is explained in the Tuner section of this guide. The remaining modes use color-coded LEDs on each footswitch button to help distinguish its current function. Where applicable, these LED colors and indications are noted.

PRESET MODE

The Preset Mode (default) allows you to select an individual preset within the current bank. When in Preset Mode, the current bank is indicated by an illuminated yellow LED on the footswitch. If the yellow LED is flashing you are in Bank Select Mode. (See Bank Select Mode, this section.)

From the Preset Mode, pressing the following buttons on the footswitch will render the listed result. Refer to the Footswitch diagram on page 17 for numerical/feature references.

Pressing button #25 selects the EFX Select Mode and exits the Preset Mode (see EFX Select Mode, this section). Pressing button #25 again returns you to the Preset Mode.

Pressing button #26 selects the Bank Select Mode and exits the Preset Mode (see Bank Select Mode, this section). Pressing button #26 again returns you to the Preset Mode.

Pressing buttons #27 through #30 select the preset in the current bank and illuminate the red Preset LED.

24. MIDI OUT

The MIDI Out five-pin DIN can be used as both a standard MIDI Thru and/or MIDI Out jack. Program changes sent to the Transformer via the MIDI In jack are echoed thru the MIDI Out. Refer to the MIDI/Footswitch section and the Application Notes for more information on this feature.

The Green LEDs dimly indicate that the effect (written below the LED) is either in primary or secondary position as selected in the EFX Select Mode. (See EFX Select Mode, this section).

The Red LEDs indicate the current preset (1,2,3 or 4).

The Yellow LEDs indicate the current bank (A,B,C or D).

BANK SELECT MODE

Pressing the Bank Select Button (26) from the Preset Mode enters the Bank Select Mode. The Bank Select Mode allows you to select an individual preset bank (A,B,C or D). A flashing yellow LED indicates the current selected bank and that you are in Bank Select Mode.

From the Bank Select Mode, pressing the following buttons on the footswitch will render the listed result. Refer to the Footswitch diagram on page 17 for numerical/feature references.

Pressing button #25 selects the EFX Select Mode and exits the Bank Select Mode. (See EFX Select Mode, this section.)

Pressing button #26 will return you to the Preset Mode.

Pressing buttons #27 thru #30 select the bank and illuminate the yellow Bank LED.

The Green LEDs stay the same as they do in the Preset Mode. (See Preset Mode, this

section).

The Red LEDs stay the same as they do in the Preset Mode, except in this mode they indicate the current preset number and the preset number (not bank) you will be relocated to once the new bank is selected. For example, changing banks while currently at preset A4 will only allow you to go to the A4, B4, C4 or D4 positions from the Bank Select Mode. This can be changed to go to A1, B1, C1, D1, or wait for your selection. (See Hot Key Chart page 22.)

The Yellow LEDs indicate the current bank (A,B,C or D) by flashing on and off.

EFX SELECT MODE

Pressing the EFX Select Button (25) from the Preset or Bank Select Modes enters the EFX Select Mode. The EFX Select Mode allows you to toggle between primary and secondary preset parameters. The green EFX Select Mode LED illuminates to indicate that this mode is active. To exit the EFX Select Mode, press the EFX Select Button (25) a second time.

From the EFX Select Mode, pressing the following buttons on the footswitch will render the listed result. Refer to the Footswitch diagram on page 17 for numerical/feature references.

Pressing button #25 will return you to the Preset Mode.

Pressing button #26 sets the delay tempo. It must be pressed more than once to record a

delay rate change. It is possible to use this button in conjunction with the Tap Tempo Button (16) on the front panel of the Transformer 112 in order to achieve rather short delay times.

Pressing button #27 toggles between the primary and secondary boost settings. (See EFX Select Mode in the Application Notes page 16.)

Pressing button #28 toggles between the primary and secondary modulation settings. (See EFX Select Mode in the Application Notes page 16.)

Pressing button #29 toggles between the primary and secondary delay settings. (See EFX Select Mode in the Application Notes page 16.) Pressing button #30 toggles between the primary and secondary reverb settings. (See EFX Select Mode in the Application Notes page 16.)

The Green LEDs stay the same as they do in the Preset Mode. (See Preset Mode, this section.) NOTE: The Tap Tempo LED flashes to indicate the current delay rate.

The Red LEDs stay the same as they do in the Preset Mode, except in this mode they become more dim in order to not confuse you during the EFX Select process.

The Yellow LEDs indicate the current bank (A,B,C or D) of the current preset. The current bank’s LED will become dim in order to not confuse you during the EFX Select process.

TUNER MODE

Pressing both the EFX Select Button (25) and the Bank Select Button (26) from any mode (except from the Tuner Mode itself) will enter the Tuner Mode. The four yellow LEDs will light dimly to indicate the Tuner Mode is acitve and awaiting a signal. This section will only describe the footswitch functions of the tuner. Refer to the beginning of the Application Notes to get a more thorough explanation of the Transformer’s tuner function.

From the Tuner Mode, pressing any footswitch button will exit the tuner and return to the previous mode and preset.

The Green LEDs indicate the current note the tuner is tracking. When in chromatic mode, if the played note is not an E, A, D, G or B then the tuner will light the two green LEDs that the played note falls between.

The Red LEDs work in conjunction with the yellow LEDs to form a ring. When a note is being tracked, the red and yellow LEDs illuminate progressively in a circle. If the LEDs light in a counter clockwise rotation then the note is flat. If the LEDs light in a clockwise rotation then the note is sharp. If they rotate quickly then you are far from having the note tuned. If they rotate slowly then the note is near its tuned state. When the note is tuned, all red and yellow LEDs will illuminate simulatneously, making it very obvious.

The Yellow LEDs always light up dimmly when the tuner is first activated. Once a note is played they act as the red LEDs do above.

31. REMOTE CABLE CONNECTOR

This eight-pin DIN is used to transmit and receive MIDI commands to and from the Transformer MIDI In/Footswitch (23). Certain functions, such as the tuner, are also communicated through this connection. Only Peavey’s eight-pin MIDI/Communication combo

cable (included) should be used for this connection.

Application Notes

This section provides short tutorials demonstrating various features and operation scenarios. Since tuning is generally done before playing, let’s learn how to use the built-in strobe-style tuner. You should complete steps 1 - 6 of the Quick Start section on page 3 before beginning this tutorial.

uner Notes

Your Transformer features a dual-mode tuner which can be viewed from both the front panel of the unit and/or the footswitch. The two tuner modes include guitar and chromatic. Let’s first take a look at how the front panel and footswitch “transform” to display the tuner functions.

Front Panel

You may access the tuner function from any mode while the amp is on by pressing both the STORE and USER buttons simultaneously. The default tuner mode is the guitar mode. (See Guitar/Chromatic Modes on next page). The diagram below depicts the functional transformation that occurs to the front panel LEDs when the tuner is activated. In the diagram, the letters listed above the LED rings correspond to the six strings of a six-string guitar tuned to a standard tuning.

TUNER/LED TRANSFORMATION ON FRONT PANEL:

NOTE: The same front panel features/functions are used

for both the guitar and chromatic modes.

The faster the rotation the more out of tune.

Footswitch

The footswitch, when plugged in, works simultaneously with the front panel. Since it doesn’t have in common the LED rings that the front panel has, the footswitch must do some transforming of its own. Refer to the diagrams below to see which LEDs and switches play a role in tuner use.

To access the tuner function from the footswitch, press both the EFFECTS SELECT MODE button and the BANK SELECT MODE button simultaneously. The footswitch indicates that it is in Tuner Mode by dimly illuminating all four yellow bank LEDs. In the diagram below, the letters listed above the footswitch LEDs correspond to the six-strings of a six string guitar tuned to a standard tuning. Unlike the front panel, the footswitch is labeled E, A, D, G, B and E (top left to right) to aid in quick, remote tuning. These labels designate the note represented by the green LED below it. Upon striking a note, a green LED will illuminate just as the LED ring did in the front panel description. Though the green LEDs function in both guitar and chromatic tuning modes, they will respond differently. See the following section for a description of the two tuning modes.

Master Footswitch Tuner Indicators/Controls:

Secondary Tuner Indicators:

E A D G B E

Press these two buttons simultaneously to activate the tuner from the footswitch. Press any button to exit the tuner.

These single LEDs light up to indicate the current note

being tracked. In chromatic mode, if the current note is not E,A,D,G or B

the tuner will indicate the two notes which the current

note falls between.

See next diagram for explanation of this

highlighted area.

These two rows of LEDs form a single LED ring like those found on the front panel. The note LEDs (EADGBE) found in the Master Footswitch diagram above depict the note that the LED ring is currently tracking (see dashed line).

counter clockwise = flat

clockwise = sharp

All eight LEDs lit indicates

a note in tune

NOTE: Four illuminated yellow LEDs and no illuminated preset (red) LEDs indicates that the tuner is waiting for a note to be played.

Tuning Modes

While in the Tuner Mode, press the Tap Tempo button on the front panel to toggle between the guitar and chromatic tuning modes.

In the Guitar mode, the built-in tuner acts much like a standard, auto guitar tuner. It always searches for the standard guitar notes (EADGBE) and automatically selects the notes for you. In other words, you don’t have to select a note for your Transformer to find, it tracks the current note automatically. The note indicated (lit up) by the Transformer is the closest standard tuning note in relation to the current note being played. The Transformer will indicate whether the note is sharp or flat by strobing the illuminated LEDs right or left respectively.

In the Chromatic mode, the tuner tracks all notes whether they are standard tuning or not. If you were to play an F# on the low E string, the tuner would track that F# even though it is not a standard open string tuning for a guitar. This is a handy feature which makes the built-in tuner functional for open tunings as well as tuning a variety of other instruments. The display indicates sharp and flat notes the same as it does in the Guitar mode. The main visual difference in the display occurs when you hit a note such as the F#. The display only has provisions to indicate E,A,D,G, B and E. Therefore, the tuner will light up both the E and A positions in order to indicate that the note is somewhere between an E note and an A note. The Guitar mode cannot do this since it tracks the F# note as a G note that is flat.

The Chromatic tuning mode is octave sensitive. Using the F# scenario from above, this becomes easy to explain. If an F# is played on the D string (instead of the low E), the D and G positions illuminate to indicate that the note is sharp for the D string. Whenever you see multiple green LED’s lit up on the footswitch while tuning, these same positions will light up on the LED rings found on the front panel. See the Transformer Tricks page for some power user tuning suggestions!

NOTE: If you want the tuner to remember your settings, press STORE once while in Tuner Mode.

TOP SECRET

Transformer T

ricks

This section is for the power user. If you are experienced with the traditional combo guitar amp, this section is for you! The Transformer earns its name through the incredible flexibility it possesses. In this section Peavey engineers provide you with many hidden functions not advertised or screened on the front of the unit. These are strictly free functions that were used to aid in the actual design of the Transformer. In order to prevent confusion, these functions were not listed in the features list for this product.

Swap Cabinets

One of the most unique hidden features on the Transformer is the ability to change speaker cabinets for the various amp models. For example, if you’re modeling a popular American 212 amp and you’d like to hear what that same amp would sound like with a 412 enclosure, it’s easily accomplished.

1. Select the desired preset number using the Preset Matrix Selector (5).

2. Select the desired amp model using the Amp Model Selector (8).

3. Press and hold down the User Switch for full second (6).

4. Select the desired speaker cabinet (refer to chart on page 8 using the Amp Model Selector.

5. Release the User Switch.

You have now created your own combination amplifier! Adjust the EQ and gain controls to your taste. Then, add in some effects for more dynamics. Once you are happy with the tone and levels you can save this new combination as a preset by pressing the STORE button twice. You may also save this preset to a different location by pressing the STORE button only once, selecting the desired preset location and then pressing the STORE button once again.

With this feature of the Transformer you are able to mix and match virtually any amp and enclosure available on the market in any way you desire.

Sweet Sweep Freeze

This is an unobtrusive feature that is simple to use. This feature is only available for patches that utilize the Phaser or Flanger modulation effect. These two effects function from a process called comb filtering, which effectively runs your guitar signal through a filter (pseudo EQ) that is sweeping. The rate at which it sweeps is determined by the Rate (14) control. The Sweet Sweep Freeze allows you to stop the filter from sweeping at any part in its sweep cycle, preserving the tone from that position.

Imagine that you are using a lot of Phaser effect with a very slow Rate setting. You can actually hear the effect as it makes a long “swish” sound. What it is actually doing is cutting the level to a certain frequency, similar to pulling down the slider on a graphic equalizer. However, the frequency it cuts is constantly changing or sweeping. This would be comparable to grabbing the sliders on an equalizer and moving them up and down quickly from left to right and then right to left. Now imagine that whole sweep cycle as the word “swish”. During the “sw” portion of the swish cycle, the high frequency content of your guitar tone is washed out and reduced to almost nothing. As you approach the “wis” portion of the swish cycle, your mid frequency content becomes more apparent. A slight increase in highs can also be noted. As the cycle approaches its end or the “sh” portion, both the highs and mids are very evident in your guitar tone.

TOP SECRETTOP SECRET

TOP SECRET

This effect causes your tone to sweep in and out from a somewhat mellow, rolling tone to a more dynamic, present tone. Sweet Sweep Freeze allows you to stop the sweep anywhere in its cycle and freeze the tone at a desired spot. This is really cool since it can all be done from the footswitch once some specific settings are made on the front panel.

1. Pull up a preset with the Flanger or Phaser modulation effect in the patch [or switch

to it with the EFX Select Modulation Switch (28)].

2. Place the footswitch in Effects Select Mode by pressing the EFX Select Mode

Button (25).

3. If the green Modulation LED (on footswitch) is not lit press the Modulation Button (28)

once to select the secondary position. If it is lit move to step 4.

4. Adjust the Depth (15) control on the front panel for the amount of effect you desire.

5. Adjust the Rate (14) control on the front panel to the desired rate or speed.

6. Press the Modulation Button once to turn the LED off and change the effect to its

primary settings.

7. Turn the Depth setting to the same setting as in the secondary mode but turn the

Rate all the way down, effectively turning the sweep off. This leaves the effect (filter) in the signal path but doesn’t allow it to sweep. Put another way, it is frozen.

8. Press the Modulation Button once more to activate it’s secondary (sweeping)

setting.

9. You should be able to press the Modulation Button at this time and toggle between

the your desired modulation effect and frozen filter position.

Notice as you play through the Transformer, toggling the modulation effect between primary and secondary settings, the Sweet Sweep Freeze function freezes the filter at whatever position it was in the cycle and maintains that tone until you activate the effect again. Upon activating the effect, the cycle picks back up where it left off.

The Sweet Sweep Freeze effects is especially useful because it allows you to punch in and out of the modulation effect without hearing the drastic difference in guitar tone that is reminiscent of the old phaser/flanger effects. Since the guitar stops the sweep and plays the sound that was last heard there, effectively, is no tone change. In addition, it allows you to wait for a killer tone to come up in the sweep cycle and then lock on to it immediately. The Transformer will not remember that freeze point for future recalls of that preset. This is simply a means of freezing a tone within an active preset. Here’s a tip for freezing tones. Before switching the modulation effect off and freezing the tone, it is easier if the Rate is set to about the 9 o’clock position and the Depth to about the 12 o’clock position. This allows for bigger and longer sweeps, giving you more time to freeze the signal.

wo Steps to Half-Step Tuning

The Transformer also allows you to tune your guitar a half step lower (E). This E tuning is very popular and can be easily mastered using this quick function.

1. Press the STORE and USER buttons simultaneously to enter the Tuner Mode.

2. Press the USER button once more to “Transform” the tuner from E tuning to E. (If the USER LED is lit, the E tuning is already enabled.)

All LED rings (the entire tuner) have been shifted a half step to measure for E tuning. The tuner will remain in E tuning until you exit and must be put back into E tuning if so desired during the next tuning session. (Unless you press STORE while in the tuner, which will store your tuner settings.)

Once a Gain

This feature allows you to get another boost of gain from your Transformer. If a single-button footswitch (Peavey part #5100) is inserted into the Low Gain input on the front panel of the amp (with a guitar plugged into the High Gain input) you can access an extra gain boost rather comfortably. This is especially useful if you have two guitars with different output levels. The footswitch must be the push on/push off type and utilize a shielded cable. A momentary switch of this nature is not recommended. Simply press the button on and off while playing to determine which position has the higher gain.

Store Tuner Tweaks - Tuner will not remember your preferences unless you save them. (Just press once). E mode - Press the USER switch to toggle between E and E mode. The LED will be lit for E mode. All notes are moved up on the display - even in chromatic mode. We offer this since E tuning is so popular among guitarists. Chromatic mode - Press the TAP switch to toggle between guitar and chromatic mode. The LED will be lit for chromatic mode. We offer this so you can use open tunings and not have to bring a separate tuner. Tuner Volume - Defaults to 12:00 position. Turn up or down to change the bypass volume level while tuning. Turn all the way down for silent tuning.

Transformer

MIDI Implementation

The Transformer is designed to be an all-in-one guitar amplification system using the PFC 4 footswitch. However, the numerous other uses for the MIDI jacks will be discussed here. We’ll start with the simpler stuff, and move on to the more complicated stuff later.

MIDI Channel on the T

ransformer

The Transformer’s MIDI channel is 1 by default (after re-initialization). This means that any channel messages that are received on another channel are ignored, and any channel messages that are generated are sent on this channel. To change the channel, hold the STORE button down for at least a second, and (while holding) select channel 1 - 16 using the Preset Matrix selector.

MIDI Out as a MIDI Thru

Most likely, you’ll be using the PFC 4 to drive the MIDI In, since it adds so much to the usability of the amp. If you decide to link another Transformer up for stereo operation, you can have the second one be slaved to the first one’s PFC 4 by connecting a MIDI cable from the first’s Out to the second’s In. They will track program changes, EFX mode changes, TAP tempo, other preset edits, etc. Even if the audio link is from the first's effects send to the second’s effects return, it’s still useful to have the same presets in the second amp and link them since the Amp Model selection (which changes per preset) affects the voicing of the power amp.

The MIDI Out jack will echo virtually all commands that arrive at the MIDI In (with the exception of certain Sysex messages meant for the Transformer), so it can be used in the middle of a MIDI chain when driving a rig from another MIDI source, instead of using the PFC 4. This is called a “soft” thru, which means it is dependent upon the software (processing power and MIDI buffer) of the unit. A “hard” thru refers to a jack labeled “Thru” and not “Out” or “Out/Thru.” It’s usually accompanied by a separate MIDI In and Out, and it’s usually in the middle. Most importantly, it’s directly driven from the In jack, so it is not dependent on the software to do the echoing work. So if your other MIDI units are “three-jack” units, it may be wise to put the Transformer at the end of the chain, since a soft thru is never quite as bulletproof as a hard thru.

Preset Synchronization with an External Effects Unit

You may have a programmable effects unit with a MIDI In that you want to use in the Transformer’s effects loop. If you want this unit to change presets when the Transformer does, connect a MIDI cable from the Transformer’s MIDI Out to the MIDI In of the effects unit. Then the first 16 presets in the effects unit will be aligned with the 16 presets in the Transformer.

For this to work, the MIDI channel of the effects unit must either be set to OMNI, or match that of the Transformer.

Preset Backup

You can back your presets up to a computer, sequencer, or other type of MIDI librarian/recorder. You can also transfer them to another Transformer! Connect a MIDI cable from the Transformer’s MIDI Out to the MIDI In of the recording device. Prepare the recording device or software program to receive data. (In the case of transferring to another Transformer, it just needs to be on.) You are now ready to send the presets.

To initiate the transmission manually, hold the amp’s TAP button and then press the MODULATION Select button. The six Amp Model LED rings (Pre Gain through Reverb) should go off for a second or two to verify the operation. When they come back on, the operation is done.

NOTE: The size of the System Exclusive preset dump is 1000 bytes.

If your recording device can send a request string to automate this operation, the string can be found in the SysEx table below. Another cable will have to go from the Recorder’s Out to the Transformer’s In for this to work. Sending that string to the Transformer will initiate the dump operation.

To dump globals: hold TAP and press STORE To dump a single preset: hold TAP and press USER

Channel

Messages

The Transformer will accept (and echo) the following channel messages when they are sent on its MIDI Channel. (Values are shown in hexadecimal.):

• Program Change - Cx nn where x = MIDI channel - 1, nn = 00-0F for presets A1 - D4

• Bank Select - Bx 20 nn where x = MIDI channel - 1, nn = 00 for factory, 01 for user

• Main Volume - Bx 07 nn where x = MIDI channel - 1, nn = 00-7F for mute to full

NOTE: The Main Volume will be located after the preamp and EQ and before the time-based effects.

Other channel messages will be echoed to the MIDI Out, but will not affect the Transformer. The Transformer will generate the following channel messages on its MIDI Channel:

• Program Change (as shown above) - whenever a preset change is initiated by front panel or PFC4.

• Bank Select (as shown above) - whenever the MATRIX bank is toggled from/to Factory to/from User.

System Common and System Real T

ime Messages

The Transformer will echo these messages to the MIDI Out when received. None will be generated by the Transformer.

System Exclusive Messages

The Transformer is equipped with an extensive MIDI SysEx implementation. In addition to simple preset dumps and preset sharing via the Internet this enables the amp to be programmed remotely by a computer program or hardware editor like the Peavey PC1600X.

All of the Transformer’s SysEx messages start with a common header and end with an End of Sysex [EOX] byte. The table below shows the “unique” section (including the command and optional data) of each message that falls between the header and the EOX.

Here is the common part, along with descriptions of each byte’s purpose: F0 - Start of SysEx [SOX]

00 00 1B - Peavey Manufacturer ID = 00 00 1B 10 - Transformer Product ID 00 - Reserved for future use (keep fixed at zero) CMD - Command byte that defines which SysEx message it is <data>- Optional data F7 - End of SysEx [EOX]

NOTE: Each time a preset is recalled, it is first loaded into a RAM buffer that we call the Edit Buffer (could also be called “current preset”). If another preset is recalled, the Edit Buffer is erased, so any changes will be lost unless stored to a User location (or externally). In the table below, we refer to this preset location as the “EdBuf.”

* Nibblized data is sent hi nibble, then low nibble. For example, a hex byte value of 74 will be

sent as two bytes: 07 04. This is because MIDI data bytes really only have seven bits - the most significant is reserved to be set for status bytes only.

** Partial addressing is a way of programming a portion of an EdBuf byte, while not disturbing

the other bits in that byte. A Partial address is made up of three bytes. The first is the byte address of the preset byte you are targeting (00-1E). The second byte is the bit number you want to start writing at (0 for least significant, seven for most significant). The third byte defines how many bits you want to program. The next byte will be the value, and since it is a partial, it does not need to be nibbleized. For example, to set the Delay Rolloff bit, send the following string:

F0 00 00 1B 10 00 0E 1D 07 01 01 F7

The 1D points to the Delay Separation Byte, whose bit seven is used for the rolloff flag. The 07 says that we’re poking bit #7. The first 01 says that we’re programming one bit. The second 01 says that we’re setting (vs. clearing) the bit.

*** “Current” addressing is an alternate method of controlling the ten preset parameters that have

dual settings. Instead of the programming device needing to have two different strings for the two levels of, say, Pre Gain, it can use these messages with the address of the first Pre Gain parameter, and the status of the Boost will determine which of the two bytes will actually be read or written. For example, ten sliders (out of 16) of a PC1600X can write current Pre Gain through Delay Level, and four of the PC1600X’s buttons could emulate the EFX Select Mode of the PFC4. Then, all 20 levels could be edited with ten sliders, instead of needing 20 (which the unit does not have).

**** This message sends a Receive EdBuf message so it is less destructive upon return to the

amp (overwrites the EdBuf). If the Receive Single Preset message is sent to the amp, it overwrites a User preset. A PC program can easily modify the header if this is the desired result, or follow up with a Store command (0A).
