Revv Owner’s Manual - 1
INTRO
Congratulations and welcome to the Revv family! Thank you for trusting
Revv Amplification with such an important part of your musical endeavors.
Enjoy tone, durability, and ease of use designed to inspire.
Please note that this manual applies to both our Dynamis head & combo
amplifiers. They feature the same tone & controls - the only difference is in
setup & safety instructions given the combos have built in speaker(s). The
short version is to leave the speaker plugged into your combo, & never
turn on your head without using the right cabinet.

1.1
set up & power up
Only keep your Revv in a dry place that keeps 6” of space between the
rear and any other objects. Tubes produce heat, and anything flammable
should be kept away.
First, make sure that the power and standby switches are in the off (down)
positions. Next, connect the AC power cord to the amplifier Mains connector on the rear of the amplifier - then to an AC outlet. At this point, all
other peripherals can be connected to the amplifier as well: Foot Switch,
FX Loop, Guitar, and cable
Note: A high quality, shielded instrument cable is recommended for guitar
input as well as FX loop connections to prevent unwanted noise.
Once all your connections are made, move the power switch to the On
position and give the tubes at least one minute to warm up. Now is a great
time to begin setting all controls while we wait. We recommend setting
the master volume, channel level, and gain controls to the lowest setting
or zero (fully counterclockwise) and all treble, mid and bass controls to the
12 o’clock positions to begin. Now set the standby switch to the Revv (up)
position and you are ready start!
Note: Upon power up, you will notice that all LED’s light up for a couple
seconds and then only the Channel 1 LED remains lit. This is normal as the
amp does a start up sequence at power up, then arms channel one to
begin.

Front Panel Layout
2.1
Input
1/4” Instrument cable input.
Low Input
This input jack is to be used with guitars that have high output or active
pickups if you desire a cleaner sound & it provides the proper circuit to
keep the tone of the amp articulate & prevent unwanted compression &
noise. If you are finding the tone weak to your personal tastes - do not
hesitate to plug any guitar into the normal input to experiment with new
sounds. This operation is safe & will just hit the front end of the amp
harder if you are going for that sound.
Normal Input
This input jack is to be used with guitars that have passive pickups &
require high impedance for proper signal transfer. This jack is designed
to get the strongest signal from a passive pickup to the first tube stage.
Revv Owner’s Manual - 6
2.2
Channel One (Clean)
Selected by: 1) pushing the designated front panel momentary toggle
switch up (LED turns blue), 2) footswitch button #1 or a footswitch
preset mode setting, 3) MIDI & CC commands.
Passive treble, middle, bass, & level controls with a wide range. Small
turns = large tonal change!
Bright changes top end response for a more sparkly tone. It is normally
best to choose the bright setting you prefer (on or off) & then dial treble
to taste. Also useful when switching between humbuckers & single coils!
Very warm & full-bodied clean channel. Takes pedals very well - or
decrease power to 7 watts for a more broken up sound with the Output
Power Switch. Channel output power is independent so you can use
this to control both tone & volume separately from the gain channel.
Revv Owner’s Manual - 7
2.3
Channel Two (Distortion)
Selected by: 1) pushing the designated front panel momentary toggle
switch up (LED turns red), 2) footswitch button #2 or a footswitch preset
mode setting, 3) MIDI & CC commands.
Gain, treble, mid, bass & level (volume) control knobs with a wide range
of operation - small adjustment = large tonal change!
The Dynamis contains 3 Dynamic Levels: crunch (green), open gain
(blue), & warm high saturation (red). This is an idea we borrowed from
the Generator’s Aggression Modes & applied to the Dynamis’ vintage
tones. You could easily cycle through these for crunch, rhythm & lead, or
find the mode you like the feel of best & always use it for all of your gain
tones!
Revv Owner’s Manual - 8
These dynamic levels can be cycled through both by repeatedly pressing the designated momentary toggle switch & by repeatedly pressing
the Channel #2 footswitch.
The amplifier has a midrange focus & to modify this you can either slightly dial back the mid control or switch between the two Contour options
for a bright upper-mid focused sound (on) or a thick lower-mid focused
sound (off).
The Bright switch also controls Channel 2 (independently) & as above
can be set to taste to help you find your desired top end response.
As with Channel One, Channel Two has an independent 40 watt / 7 watt
Output Power Switch. 7w mode will help achieve satisfying sounds at
lower volume and/or give you the option of a tone featuring more power
amp saturation. All else being equal this will result in a more broken up
oldschool sound, compared against letting the preamp take care of
much of the gain in the higher headroom 40w mode.
Revv Owner’s Manual - 9
2.4
Reverb, Level, & Decay Switches
The Dynamis includes a lush onboard reverb with 3 decay lengths.
These decay lengths & the level of the reverb are independently controllable per channel using the front panel controls.
Upon startup, reverb is engaged with a short decay. To turn reverb on or
off, simply press the reverb toggle switch in the up position. The LED will
turn on or off depending on the setting. To cycle through different decay
options, simply press the toggle switch down towards the decay position. The decay options are indicated by LED: short decay (off), medium
decay (blue), long decay (Red).
Note: These levels can be cycled through by holding footswitch button
#4. Reverb can be turned on & off entirely with a single momentary
press of button #4.
Revv Owner’s Manual - 10
Each channel reverb level control is independent & decay settings +
on/off states are retained for each as long as the amp is powered on.
Note: Reverb settings are also footswitch saveable options should the
foot controller be used in preset mode. See foot controller section of
this manual for more information.
2.5
Standby & Power Switch
The power & standby switches give the amp power from the mains, as
well as high voltage through the circuit. First turn on the power switch &
wait one minute to allow the tubes to warm up. Turn on the standby
switch to the Revv position once you are ready to play.
Note: NEVER power up the Dynamis Head without the proper speaker
load connected, or the Dynamis combo with the speaker disconnected!
Revv Owner’s Manual - 11

Rear Panel Layout
3.1
Main Power Connection
When plugging the amplifier into the mains A/C wall receptacle, always
make sure the amplifier power & standby switches are in the off position.
The Required voltage & fuse ratings are marked on the amplifier, verify
that they are correct before plugging in.
Main & HT Fuses
The mains fuse & HT fuse are in place to protect you & your amplifier
from overload conditions. Always replace them with the same type &
rating only! Always unplug the amplifier from the mains before replacing
the fuses. Fuse requirements are marked on the rear panel of the amplifier.
Revv Owner’s Manual - 12
3.2
Bias Test Points
This amplifier is designed to allow the user to set the bias of the power
tubes without removing the chassis from the head shell.
Each pair of power tubes needs to be set according to the tubes being
used.
Power Tube Fault Fuses
The power tubes are fused in pairs. Should a power tube fail, the fuse will
blow & take the pair of power tubes out of service. This has the benefit
of protecting the amplifier, & also allows for continued playability, so as to
allow the user to finish the gig on the remaining pair. The volume & tone
will change but the show will go on.
Note: Should the amp be run with 2 power tubes removed from service
(bad or blown fuse), in order to achieve a tone more consistent with
normal 4 tube operation the amp should be run with an impedance
setting of half the speaker cabinet rating. For example, if the speaker
cabinet is 8 ohms, set the amplifier to 4 ohms, & if the speaker cabinet is
16 ohms, set the amplifier to 8 ohms.
Revv Owner’s Manual - 13
3.3
Impedance & Speaker Jacks
The amplifier must always be connected to a speaker cabinet or load
when it is powered up. This amplifier can be used with cabinets that
provide a load of 4, 8 & 16 ohms.
Note to combo users: The combo can only be used with external cabinets of 4 or 8 ohms
Because the amplifier provides multiple speaker jacks, it can also power
2 cabinets directly from the amplifier, but the impedance will need to be
set correctly.
Most setups are simple, one cabinet plugged into the amp, set the
impedance to that marked on the cabinet & you’re ready to go! However, when it comes to adding more cabinets to the rig, more care must be
taken to prevent damage. Most rigs will not utilize more than 2 cabinets
so we won’t go beyond 2 cabinets here.
Revv Owner’s Manual - 14
Some multi-cabinet head examples:
2 - 8 ohm cabinets would be run to the amplifier (one per speaker jack),
the correct impedance would be 4 ohms as they are being run in parallel.
2 - 16 ohm cabinets would be run to the amplifier (one per speaker
jack), the correct impedance would be 8 ohms as they are being run in
parallel.
2 - 4 ohm cabinets cannot be run in parallel with this amplifier. This will
cause damage.
Note: No damage will result when running the amplifier set at a lower
impedance (Ex: 4 ohms) into a cabinet rated at a higher impedance (Ex:
8 Ohms). However the opposite will possibly cause damage to the
output transformer or other components & it is suggested that the
amplifier never be run into a lower load than what the amplifier is set to
when hooking up speakers in different configurations.
Some combo examples:
1 - 8 ohm cabinet AND the provided 8 ohm combo speaker: In this configuration, plugging the provided speaker into one of the 4 ohm jacks &
the 8 ohm speaker cabinet into the other 4 ohm jack will provide the
perfect load to maintain the best possible tone & keep the amplifier safe
from harm. The 8 ohm jack MUST NOT be used!
2 - 8 ohm cabinets: In this configuration, one of the 8 ohm cabinets
would be plugged into a 4 ohm jack, & the other 8 ohm cabinet would
be plugged into the remaining 4 ohm jack. The provided speaker MUST
be disconnected from the 8 ohm jack, & the 8 ohm jack MUST NOT be
used.
Revv Owner’s Manual - 15
1 - 8 ohm cabinet WITHOUT the provided 8 ohm combo speaker: In this
configuration, the provided speaker would be disconnected from the 8
ohm jack & the 8 ohm speaker cabinet would be plugged into that same
jack. The remaining 4 ohm speaker jacks MUST NOT be used. The provided speaker cannot be used in this configuration & must remain
disconnected.
1 - 4 ohm cabinet: In this configuration, only one 4 ohm speaker cabinet
can be used with this amplifier. The provided 8 ohm combo speaker
MUST NOT be used, the remaining 4 ohm and 8 ohm speaker jacks
must also NOT be used.
2 – 4 ohm cabinets cannot be run in parallel with this amplifier. This will
cause damage.
3.4
FX Loop Connections
The FX loop connections are to be hooked up to external pedals or
effects units. The Send level will supply the signal required & needs to
be set accordingly with the send level control.
Revv Owner’s Manual - 16
MIDI Connections
Note: The Dynamis Combo does not include midi.
The MIDI IN connection is for external equipment connections when
your rig necessitates control of your Revv with third party gear.
Foot Switch Connection
This connection both powers your footswitch & allows it to control your
Revv.
Should the provided footswitch cable fail, any Ethernet cable can be
used. However, this cable sends data between the amplifier & footswitch
& if a lower quality cable is used incorrect switching or erratic behavior
may occur. A high quality cable is recommended, which can be provided
by Revv should you need a replacement.
Speaker Cab Lighting
Revv speaker cabinets each have an illuminated up logo which is powered from the cab lighting jack on Revv amplifiers. This is a 4 pin DIN jack
that should be connected to the 4 pin DIN jack of a Revv speaker cabinet
only. The logo will change colors in conjunction with the channel switching of your head.
Note: This jack can only be used with Revv speaker cabinets.
Solo Level Control
This knob sets the level of the Dynamis’ solo boost which is engaged
when pressing button #3 on the footswitch. You could also use this to
reduce volume.
Revv Owner’s Manual - 17
4.0
Serial Effects Loop
This effects loop is foot switchable, preset recallable, & MIDI + CC controllable. It has also been given an On & Off control ability to have the
send level control & FX Loop jacks removed from the signal path entirely
- even though it was designed from the start to be as transparent as possible.Tube driven with the send output buffered at 900 ohms.
4.1
4.2
FX Loop On/Off
The amplifier’s footswitch (button #5 in control mode) is used to switch
the effects loop in & out of the signal path to make it easier to apply &
remove effects to the guitar signal on the fly.
If you do not use the footswitch, the FX loops will always default to an on
state. If the footswitch is plugged in - the FX loop defaults to off unless activated via the footswitch.
Midi will always be able to control FX loop state as well.
SEND Level Control
This effects loop has a Send Level control to make sure your effects
volume is optimal. Always make sure to check this knob if you are experiencing any overly loud, or quiet effects - or level issues of any kind.
If your effects start clipping - you are driving the loop too hard with this
control.
Revv Owner’s Manual - 18
Note: The level controls on each channel will also affect the send level
being sent from the effects loop - when one is set higher than the rest
you will find your signal changes when using that channel. Be sure to test
each channel & the send level coming from the effects loop. For this
reason it is normally preferable to set the level of your channels first then
adjust your effects loop send level.
4.3
FX Loop Hook up
First, you need to hook up your effects units to the amplifier. The send
jack will need to be connected to the input of the first (or only) effects unit
in your chain. The out jack on the effects unit (or last pedal in your chain)
will then connect back to the return jack on the amp.
Adjust each channel’s level control to your liking & set your send level
control as above.
Note: If you hear no sound - your effects loop level control knob is probably set at zero, or your FX loop is disabled! Refer to the above on/off section.
Revv Owner’s Manual - 19
5.0
Tubes & Bias
5.1
5.2
Power Tubes
Our lower wattage amplifiers are designed with 6V6 tubes for the best
tonal & feel performance at a wide range of volumes. REVV-brand 6V6GT
tubes are always recommended when replacement is required.
Note: While we designed the amplifier to be easy to maintain, we advise
that all tubes be set up by a qualified service technician to prevent
damage to the amp from improper bias settings.
Preamp Tubes
This amplifier uses 12AX7 preamp tubes in tube positions V1 V2 V3, & V5.
A 12AT7 preamp tube is used in the V4 position for the FX Loop & only a
12AT7 tube should be used in this socket.
5.3
Preamp tubes do not need to be biased & usually have a long life unlike
power tubes, but it is possible for a preamp tube to become faulty at any
stage of its rated lifespan.
Power Tube Bias
The power tubes can be biased without taking the chassis out of the
wood head shell. You will need a voltmeter or digital multimeter set to the
lowest DC voltage range. (Make sure you refer to the meter’s user
manual).
Note: Use tubes that are matched! A matched quad is best but matched
pairs will also suffice.
Revv Owner’s Manual - 20
To prepare:
1) Remove the rear baffle cover from the rear of the amplifier. If you are
replacing tubes, do so now with the power off & the amplifier unplugged
from the main power receptacle. Place the new tubes in the correct
socket positions.
2) Next unlock the bias trimmers by turning the nut counter clockwise &
then turn the trimmers down by turning the trimmer shaft with a small
screwdriver in the counterclockwise direction. If any fuses had blown,
make sure to replace them as well.
3) Now plug the amplifier into the main power receptacle, make sure the
amplifier is plugged into a load or speaker cabinet, unplug any guitar
cables from the inputs & turn on the main power. Let the tubes warm up
for one minute
5.4
4) Turn the volume controls to zero & turn on standby to the Revv position.
Set the bias:
1) Place the black lead from your meter into the black bias test point on
the amplifier & the red lead into the red bias test point (The red test point
on the left is for V1 & V3 tubes, red test point on the right is for V2 & V4
tubes).
2) Refer to the chart below for bias set points for the tubes being used &
slowly turn the trimmer in the clockwise direction until the value is
reached.
Revv Owner’s Manual - 21
3) Next, place the red lead into the other red bias test point & repeat step
2 for the other set of tubes.
4) Re-check the settings of each bias test point & make any further
adjustments as required.
5) Once the bias is set at the required settings, lock down the trimmer
lock nuts by turning the nuts clockwise while holding the trimmer shaft
with a screwdriver so as not to lose the setting. Do not over tighten the
nuts, just snug them. Once complete, return the rear baffle panel to the
rear of the amp & fasten it with the screws you removed. You are done!

MIDI
Note: Combos do not include MIDI.
Versatile & optional MIDI control helps Revv amps seamlessly integrate
into any rig. The amplifier will store up to 128 programs for program change
commands as well as accept Continuous Controller (CC) commands to
control functions directly. The amplifier also features OMNI mode to allow
control options on 16 channels.
What does that mean?
1) You can set up “presets” of switch positions on the amp to recall quickly.
(this could be used for clean, crunch, rhythm, & lead, for example)
2) You can simply control anything’s on/off state (FX loop for example)
3) You can do a combination of both of those things.
Revv Owner’s Manual - 23
4) You can do this with a computer for automatic changes during songs,
a MIDI floor control unit instead of our footswitch, a loop switcher with
midi to control pedals as part of the “presets,” a multi-effects unit with
MIDI control, & more.
5) You can do this with just our footswitch, or not at all, if you choose.
External equipment just becomes more beneficial when integrating your
Revv with additional pieces of a rig such as effects units.
6.1
OMNI Mode
OMNI mode off will allow the amplifier to be controlled via a designated
channel (1-16), & OMNI mode on will allow the amplifier to respond to
commands on any channel.
If other equipment is being used in a MIDI system, it is desirable to set
each piece of equipment to separate channels. However when the amplifier is the only piece of gear being controlled via MIDI, then setting it to
a specific channel is not really required & setting the OMNI mode on
becomes preferable.
In order to toggle OMNI mode on or off:
1) Make sure the power switch is in the off position.
2) Press & hold “contour” toggle switch.
3) With the “contour” toggle switch being held, turn on the power switch.
4) Release the “contour” toggle switch once the LED begins to flash.
Once the LED has stopped flashing, it has accepted the command to
adjust OMNI mode. The amplifier will adjust to OMNI mode & then reset
itself by completing its startup sequence. Once the start-up sequence is
done (2 seconds) & the CH1 LED is illuminated, you are ready to go.
Note: The “contour” LED will flash 3 times when it turns OMNI mode on,
& 4 times when it turns OMNI mode off.
Revv Owner’s Manual - 24
6.2
MIDI Channel Setting
This amplifier can either automatically or manually change the 16 MIDI
channels you would like it to respond to. The channel change is stored in
memory & only needs to be done when you need the amp to respond on
a certain channel.
1) In order to set the MIDI channel:
With the power off, press & hold the bright switch then turn on the power
switch. The amp will power up & begin to flash 4 LEDs. Once this happens it is awaiting the channel data to be received from the external
equipment (Automatic) or to be set manually.
2a) To set the channel automatically: (recommended)
With your external equipment ready (pedals, computers, etc.) & set to
the channel you want the amplifier to be controlled from via MIDI, send a
command to the amplifier by pressing a program change button or CC
command on your external equipment. Once the amplifier receives the
data, it will verify the channel it received & save it to memory. Easy!
2b) To set the channel manually:
Once step 1 has been completed above & the channel LEDs are flashing,
press the Channel toggle switch (up). The Channel will flash & the other
LEDs will turn off, this signifies that MIDI channel 1 has been selected.
Simply continue to press the CH 1 toggle switch (up) to get to the channel you desire. As you press the switch you will notice the other LEDs turn
on as you increase the MIDI channel number. Once you reach the channel you desire, press the bright switch to save it to memory.
Revv Owner’s Manual - 25
Note: There are only 4 LEDs that illuminate in the process, so the MIDI
channel count will be done in values of 4. MIDI channel 1 will be signified
by Channel LED flashing, & as you increase in number, MIDI channel 4 will
be signified by all 4 LEDs flashing, but once MIDI channel 5 is selected,
only the Channel LED will flash again. Every time you reach MIDI channel
5, 9, or 13, the LED cycle will once again. So keep count as you select the
channel you desire. If you go past MIDI channel 16, the count will start at
channel 1 again.
Once saved to memory, the Channel LEDs will flash very quickly a
number of times to verify the change has been made & completed. The
amp will then restart, completing the MIDI channel change procedure.
6.3
MIDI Program Change
This amplifier can remember up to 128 program settings of the MIDI controllable functions. In order to set a program (i.e. amplifier configuration) to
be controlled via MIDI:
1) Set the amplifier to the configuration you intend to save to a program
number. (Ex: Ch: 2, Dynamic level: 2, FX Loop: OFF, etc)
2) Once the amplifier is configured as you would like, press and hold the
bright switch. The bright LED will flash & the amplifier will wait now for a
command through its MIDI IN jack.
3) Send a program change command from your MIDI Pedal or other
equipment with the correct channel & program number you intend to
have the amplifier save the current configuration to.
4) Once the command is received, the amplifier will save the current amp
configuration to that program number. The bright LED will flash 3 times &
turn off verifying that the command has been received & saved.
Revv Owner’s Manual - 26
Now, anytime you send that program number to the amplifier from your
MIDI pedal or other external equipment, the amplifier will switch to that
saved configuration. This will allow for any configuration of your settings to
be recalled with any MIDI device!
6.4
MIDI Controllable Functions
The amplifier functions that can be controlled via MIDI are as follows:
Channel Selection
3 Dynamic Levels (Channel 2)
Bright function (Channels 1& 2)
Contour Function (Channel 2)
FX Loop in/out
Reverb
Reverb Decay Levels
Solo Boost
Mute
These functions can be set & controlled in a MIDI program change setting, where one program change command will call up a configuration of
the above settings, or continuous controller commands, where a CC
command will switch any one of the functions listed above, independent
from any of the others. The CC command functions are great for things
like instant access buttons on foot pedals etc.
Revv Owner’s Manual - 27
6.5
Revv Dynamis 40w Continuous Controller Commands (CC)
In order to use CC commands, the Dynamis Functions have all been
given a designated number & on or off setting. When using & selecting a
function the number associated with the function must be used & then
the setting of the function (on or off) must also be sent. Most MIDI equipment (pedals etc) allows you to select a CC number & then designate
whether it be turned to on or off. (Consult the external equipments’
instruction manual). The following commands & their CC numbers need
only be sent an on command (0-63) as they are used to switch between
channels & dynamic levels which cannot be turned off, only changed to
a different channel or level, on & off commands sent will produce the
same result.
Function + CC Number (Hex Value)
Channel 1 Clean - 16 - (0×10)
Channel 2 low dynamic level - 18 - (0×12)
Channel 2 medium dynamic level - 19 - (0×13)
Channel 2 high dynamic level 20 - (0×14)
Decay short level 33 - (0×21)
Decay medium level 34 - (0×22)
Decay long level 35 - (0×23)
The following command will switch to channel 2 & then toggle through
the dynamic levels with each use of the command like using the
footswitch to switch to the channel & toggle through the dynamic levels.
This command will also respond to an on & off command with the same
result:
Channel two plus dynamic toggle: 24 – (0x18)
Revv Owner’s Manual - 28
The following commands control functions that are turned on & off.
These functions require an on (0-63) & off (64-127) command (byte) to
be sent with the CC number to either turn them on or off. If you are trying
to use them & are not getting them to respond, chances are you are
sending the wrong command byte ( 0-63 is OFF & 64-127 is ON).
(Consult the Peripherals instruction manual)

Foot Switch
The Revv footswitch can be configured to either operate as a normal
footswitch (with some bonuses) or a tool to quickly recall presets on the
amplifier.
Control Mode - select between clean,& gain channels, gain dynamic
modes, fx loop on/off, solo boost on/off, reverb on/off + its decay level, &
a master mute function
Preset Mode - select combinations of channel & switch positions + on/off
states that can be recalled with one button press.
Note: The footswitch will always be updated should a change be made
7.1
on the amplifier front panel. Panel controls override the footswitch.
Note: To switch between modes, press & hold footswitch button 1 for 2
seconds. The LEDs will all illuminate then switch to the settings in the
other mode. All settings will be retained when switching between modes.
Hook up
The footswitch is connected to the rear of the amplifier with a shielded
Ethernet cable & very rigid connectors. The amplifier & footswitch will
work with any Ethernet cable should you be in a pinch, but the Revv
cable is always recommended for best performance.
It is recommended that the footswitch be connected to the amp with the
power off, but should you plug it in during amplifier use, it will power up &
automatically set itself to the amps current settings. Upon power up, all
LEDs will turn on for a couple of seconds as it initializes. Once complete,
the foot pedal will set itself to the amplifier’s current configuration.
Revv Owner’s Manual - 30
7.2
Control Mode
The foot pedal will always power up in control mode. This mode works
similarly to most other foot pedals - it simply controls the functions of the
amp. Here is how the buttons respond in control mode:
Button One – This button switches to Channel 1 when the amp is not in
Channel 1.
Button Two – This button has 2 functions in control mode, it will switch to
Channel 2 when the amp is not in Channel 2, & it will change the dynamic
level of Channel 2 when already on that channel. The LED for channel two
will change according to dynamic level.
Button Three – This button toggles Solo Boost on/off. (On when LED is
illuminated)
Button Four – This button turns reverb on/off for the currently selected
channel. Reverb decay levels can also be cycled through by holding this
button for approximately 2 seconds at a time.
Button Five – This button toggles FX Loop on/off. (On when LED illuminated)
Button Six – This toggles the amp’s Mute function. (Amp muted when
LED lilluminated)
Note: Bright, Fat, & Contour functions cannot be changed via the
footswitch as they are considered to be an extension of the EQ. They
can be saved to a bank when in Preset mode however.
Revv Owner’s Manual - 31
7.3
Preset Mode
When the footswitch is in preset mode, each button can then be used to
save amp settings, much like a MIDI program change command. For
example, if you wanted to save an amp setting like: ch2, dynamic:
medium, bright: on, FX loop: in, you could save this all to one button! Then
every time you want to use this amp configuration, all you would have to
do is press that one button & the amp would change to this setting. Each
button on the foot controller can save settings.
Note: When a preset is set on the foot switch, it will not be lost if power is
removed from the amp. The Revv footswitch has memory & will retain the
settings. Each button is identical in Preset mode & will be considered
banks. Each bank can hold an amp preset.
Note: Buttons one, five, & six however, have 2 functions in preset mode.
Button one will switch between the modes (Control & Preset), & buttons
five & six will activate FX Loop In/Out & Mute in the same way as in control mode. Holding these buttons for 2 seconds will activate their abilities.
To save a preset to a bank:
1) Put the footswitch in preset mode & select the bank you want to save
to (Buttons one through six).
2) Set the amplifier to your desired configuration from the front panel of
the amp.
3) The bank LED on the footswitch you have selected will begin to blink
stating a change has been made on the front panel of the amp.
4) Once you’re finished configuring the amp, simply press the desired
bank button on the footswitch to save the setting into that bank & you’re
done! The LED will stop flashing verifying that the change has been
saved. Now every time you press that bank button, the amp will switch to
the configuration you saved to it.
Revv Owner’s Manual - 32
Note: Any change made on the front panel of the amp will result in a bank
LED blinking which means that the current bank setting is different from
that of the amps new configuration. To save the new setting press the
bank button on the footswitch (blinking LED), or, to reset the configuration & not keep the change, simply press another bank button & the
change will NOT be saved.
Note: To save an FX Loop setting in Preset Mode, the FX Loop Button
must be held for 2 seconds. This will change the state of the FX loop and
then your preset can be saved as with any other amplifier state.
7.4
Memory Reset
The footswitch memory can be cleared when it is needed. Each of the 6
banks will be returned to factory defaults. In order to reset the memory &
return the unit to factory defaults, begin with the amplifiers power off &
the footswitch plugged into the footswitch jack on the amplifier. Next,
press & hold buttons 1 & 2 down & turn the power switch to the ON position on the amplifier.
As soon as the footswitch powers up it will return all memory locations to
factory defaults as long as buttons one & two were held down properly at
power up.
