Welcome to the M13 Stompbox Modeler Advanced Guide. This guide contains in-depth details of your M13’s features and functionality. With over 80 Models and a Looper in one device, there’s a lot to work with. Our goal with this guide is to provide you with the information you need to make it easy to ﬁnd the sounds you’re looking for.

In the chapters that follow, we’ll be referring to the six Knobs that adjust the various parameters of the M13. These are located below each of the four LCD displays. On the top row left is the Model Select Knob. To the right of that are Knobs 1 and 2. Knobs 3, 4

and 5 are in the second row, left to right. Now to begin, let’s get in tune.

Tuner

To enter Tuner mode, press and hold the Tap switch for a few seconds. LCD 3 will display the Tuner. LCD 4 will display the note you’re tuning. If you’d like to tune to a reference

other than standard 440, turn Knob 3 to select from 425 to 455. To toggle between Mute

Audio (your guitar will be silent) and Bypass Audio (you’ll hear your guitar dry with no

FX), turn Knob 5.

Setup Details

1•1

Tuning is straightforward: when the graphic diamond is to the left of center, your note is ﬂat; when it’s to the right, you’re sharp. When the diamond is precisely in the center, two triangles will appear above and below it, indicating your string is in tune. To exit Tuner mode, press Tap again, or any other foot switch.

Setup Mode

To enter Setup mode, press and hold the Looper Controls switch for a few seconds. The M13’s four LCDs will display your settings, including Expression Pedals in LCD 1, Looper Levels & EQ in LCD 2, Preferences, Scenes & FX Loop in LCD 3, and MIDI, Gate & Displays in LCD 4.

Depending on the way you like to work, most of your Global settings can be left as is after you’ve set them initially. They’ll be recalled each time you power-up. In the following pages we’ll describe them all in detail.

Looper Levels & EQ

In LCD 1 you set up your expression pedal assignments. Any or all 4 FX Units in the M13 can be controlled by an expression pedal. You can use up to 2 pedals at once. Each can be assigned to an FX Unit or the Looper. You have 3 selection choices here: Pedal 1, Pedal 2, or Off. Knobs 1 & 2 set the assignments for FX 1 & FX 2, Knob 3 sets the assignment for

the Looper, and Knobs 4 & 5 set the assignments for FX 3 & FX 4.

*Looper pedal control is a global setting. FX pedal control settings are saved per Scene. See Chapter 2 for more details on how to set up heel and toe expression pedal settings.

There are two Looper Levels to set up in LCD 2. The ﬁrst is Play, which determines the volume of your Looper’s playback as balanced with your live guitar. The second is Overdub, which determines the volume of your loop in Overdub mode. To clarify, if your Overdub Level is set to 90%, each time your loop begins a new overdub its volume will be reduced by 10%, sounding quieter and quieter with each overdub pass. The default level for both Play and Overdub is 100%. Use Knobs 1 and 4 to adjust these levels, if desired.

With Knobs 2 and 5 you can adjust Looper Hi Cut and Lo Cut EQ levels. Hi Cut rolls off the high end for loop playback (@2kHz), and Lo Cut rolls off the low end (@500Hz). If

applied, this EQ affects the sound of loop playback only, having no effect on live guitar.

In LCD 3 you set up FX Preferences, beginning with FX order. The default is 1>2>3>4, left to right. If you prefer, you can set it to 4>3>2>1 using Knob 3. With this setting, your signal ﬂow begins with FX Unit 4 and ﬂows right to left. Set the FX order you prefer.

The Model Select Knob toggles between True Bypass and DSP Bypass. In True Bypass, mechanically switching relays route your signal directly from input jack to output jack, bypassing all circuitry, for absolutely no processing or conversion when bypassing all FX.

If you’re playing back a loop, however, or you want your Delay and Reverb trails to be heard when bypassing all FX, you must use DSP Bypass. True Bypass can only be activated when all of the following conditions are met:

•

True Bypass is enabled in Setup mode (via the Model Select Knob).

All 4 FX Units are in a bypass state.•

The Looper is stopped.•

Looper Controls mode is inactive (Looper Controls footswitch light is off).•

Scenes

Knob 1 toggles between Autosave or Manual Save. With Autosave, every change you make to your Scene is saved, like a real pedal board. With Manual Save, changes made to your individual FX will be saved only if you don’t change Scenes; if you do recall a Scene, all your changes will be lost. Manual Save is a good choice, however, when you want to be sure your Scenes will always be recalled exactly as programmed.

Knob 4 selects Momentary Scene or Latch Scene mode. Please see Chapter 3, Scenes Details, for more in-depth information on Momentary Scene and Latch Scene modes.

Factory Reset

You can insert the FX Loop anywhere in the signal path. Use Knob 5, LCD 3 to select your

insert point. Your choices are Pre All, Post FX 1, Post FX 2, Post FX 3, and Post All. The following are a few routing examples to demonstrate the M13’s ﬂexibility. (Be aware that multiple amps may cause ground hum - the common cure for this is a ground lift box):

•

Add an external FX unit to the M13: for example, run Vetta Comp in FX 1, U-Vibe in FX2, then assign the FX Loop to Post FX 2 and feed an external distortion pedal. That pedal’s output would return to feed FX 3 and 4 to add M13 Delay and Reverb.

Double routing: set the Loop to Post FX 1 and send an Octave Fuzz from FX1 out

•

to the front of a tube amp. Route the amp’s FX Send back into the M13 mono FX Return. Now add M13 Filter, Flange and Delay FX and send the M13 mono Out to your amp’s FX return. All the time-based FX will be post your tube amp’s preamp.

Wet/dry stereo: send a Comp or Dist model via FX Loop Send (Post FX 1) to a tube

•

amp for your dry sound. Add Panned Phaser, Ping Pong and Reverb in the M13 and set all Mix controls to 100% wet. Now connect the M13 stereo outputs to 2 other guitar amps. You’ll get wide, stereo FX left and right with dry guitar in the middle.

There may be times when you’d like to reset your M13 to its Factory settings. You may want to recall a particular Factory Scene, for example. To do a Factory Reset, ﬁrst back up

any Scenes you’d like to keep (see MIDI Backup on page 1•5), then follow these steps:

•

Turn the Model Select Knob under LCD 4 until “Rst Fact?” is displayed.

Press down on the Model Select Knob - “Reset To Factory?” will be displayed.•

To initiate the Factory Reset, press down on the Model Select Knob again.•

All Factory defaults will be reset, including Scene Presets and Global settings.•

MIDI Backup

With a MIDI interface and a sysex application, you can back up your M13 Scenes to computer. It makes it easy to build a custom Scenes library, or exchange Scenes with others. To backup your Scenes, or to dump the current edit buffer, follow these steps:

•

Turn Knob 3 to set your MIDI Channel from Ch. 1-16 or Omni (default is Ch. 1).

Turn the Model Select Knob to select “Dump All?” (to back up all 12 Scenes) or • “Dump Edit?” (to back up the current Scene in its current state).

With your computer set up to record sysex, press down the Model Select knob.

•

The M13 will transmit the sysex ﬁle to your computer, creating a backup of your Scenes that you can store and recall at any time.

To load a Scene into your M13, simply transmit the sysex ﬁle from your computer into the M13 via MIDI. This will immediately load the Scene into the M13’s memory.

Global Noise Gate

Knobs 1 and 4 in the center of LCD 4 control the Global Noise Gate. When activated, the Gate is in effect full time, for all your FX.

Knob 1 turns on the Gate and sets the Gate Threshold. Lower values make the Gate kick in at quieter levels, higher values make it kick in at louder levels.

Setup Details

1•5

Knob 4 sets the Gate Decay. Higher levels result in a longer transition from non-gated to

gated audio.

Displays

To adjust the contrast of the LCD displays, use Knob 5. Set it to a value that looks good to you. Settings from 30-50% usually work well.

When you’ve set all the M13’s Global parameters to your liking, press any switch to exit Setup mode. As mentioned previously, the next time you power up your M13, all your Global settings will be recalled.

The following are details on a few late-breaking models and features that were implemented in the latest M13 ﬁrmware. These were the result of customer requests, as well as features the development team wanted to add in the ﬁnal months of development.

Tap-based FX

Many guitarists who use time-based effects like to set their delay times to a note value relative to the song tempo, as opposed to setting delay times in milliseconds. This has been included in the M13 as Tap-based FX. To set your delay time to tap tempo, turn Knob 1 to the far right and you’ll see a quarter note symbol in the LCD. Change it to any note you like. Now tap the desired tempo and your time-based effect will sync to it. Your note value is persistent, so when you scroll through other effects it will be retained. To set your delay time to ms, turn Knob 2 to the right again, and you’ll return to Time-based mode.

Model Details

2•1

Fine-Tune Mode

When you’re in Time-based mode, you may want to ﬁne-tune your delay time to an exact number. This may be necessary to match a song’s tempo, or to set up precise stereo delays, to 240 ms and 480 ms for example. To make this easy to do, we’ve implemented Fine-Tune mode. When you want to dial in a precise delay time, simply do the following:

•

Adjust Knob 1 to set the delay time close to the desired value.

Press and hold the Tap switch and turn Knob 1 again to enter Fine-tune mode.•

You can now ﬁne-tune your delay time to the millisecond with Knob 1. •

DryThru Models

2•2

Another popular request from DL4 users was to provide a completely dry signal path when using speciﬁc Delay models with a dry Mix setting, so that no tone coloration was added. When we originally created our Tape Echo, Tube Echo, Sweep Echo and Echo Platter models, for example, we also modeled the dry path of the classic delays these models were based on. We did this because the original effects added a certain tonal character to the sound when Mix was set to dry, and many guitarists wanted that sound.

To make everybody happy, we decided to add what we call DryThru models. These four models are identical to the original models of the same name, but when Mix is at 0%, we removed the tonal coloration of the originals, giving you a ﬂat, uncolored sound.

Model Defaults

All FX in the M13 are programmed with Model Default settings. These provide you with a good musical experience when you ﬁrst load up each effect, giving you great “stock” settings for that model. Some are also pre-conﬁgured for expression pedal control, so if you have an expression pedal plugged in and assigned to an FX Unit and you select a new model, we start you off with what we think is a good expression pedal setup for it. (See the next page for more info on setting heel and toe values for expression pedals).

Mix

As with all other model details, the Mix control is set up to work like it did on the DL4, MM4 or other Line 6 product that ﬁrst introduced a particular model. In keeping with this, setting Mix to 100% sometimes engages a special setting found on the original effect,

such as vibrato in the U-Vibe, or a richer Leslie® sound in the Rotary Drm/Hrn.

Expression Pedal Details

Tube Comp

DIST LEVEL

THRESH

Almost any parameter in the M13 can be controlled by an expression pedal, as long as you’ve set up your FX Units and Looper assignments accordingly, in Setup Mode. To set up expression pedal heel and toe values for the parameter you’d like to control, here’s an example of how to do it. Let’s say you’d like to control the Mix level of a Reverse Delay.

•

Select Reverse Delay in one of the FX Units, and adjust the sound to your liking.

Plug in your expression pedal, and set it to the heel down position.•

Adjust the Mix level of the Reverse Delay with Knob 5. Set it to 0%. •

Put your expression pedal in the toe down position and set the Mix level to 100%.•

Play your guitar and work your pedal; the reverse guitar will fade in and out.•

You can repeat this with any effect parameters you like. Your expression pedal will control them simultaneously. If you get to a point where you want to start over, simply unplug your pedal from the rear panel and all unsaved pedal assignments will be cleared.

Tube Compressor Model

In addition to the 5 compressors described in the manual, which are all typical stomp

box type compressors, we also snuck in a Tube Comp model based on the studio classic Teletronix LA-2A® Optical Compressor, known for its smooth, easy to adjust, tube sound.

You’ll nd it at the end of the Distortion FX group. Here’s how it works:

Model Details

2•3

Adjust Knob 1 to set the Threshold - lower values result in more compression, along

•

with an automatic makeup gain stage dependent upon the Threshold setting.

Set the output Level with Knob 2. To use the Tube Comp model for boost only, use

•

a high Threshold value and adjust your Level as desired.

Sc e n e S de t A i l S

The M13 offers you two different ways to select your Scenes, depending on the way you like to work. Your choices are Momentary Scene mode or Latch Scene mode.

To clarify what we mean by a Scene, it’s basically the equivalent of a unique pedal board setup, which you can program yourself. It includes up to 4 active FX and another 8 FX set up but bypassed. When you select a particular Scene, a combination of 4 active FX is immediately loaded into your M13. The other 8 FX will also be loaded, but bypassed. You can switch any of the 8 FX on at any time, replacing any of the 4 you started with.

If you use an expression pedal in your rig, you should know that all of your heel & toe pedal

assignments can be stored in a Scene, so many unique combinations are possible. Here are

some details explaining Momentary Scene mode and Latch Scene mode.

Momentary Scene Mode

In Momentary Scene mode, here’s what happens:

•

When you step on the Scenes switch, the 4 LCDs will display the 12 Scene names in your M13.

You select a Scene by stepping on any of the 12 A, B, C switches that correspond with

•

the Scene names in the LCD. The Scene you choose will be loaded immediately.

Scenes Details

3•1

You will now see the 4 active FX displayed in the 4 FX Unit LCDs. You can tweak

•

the parameters of each, if you like, or you can activate any of the bypassed FX.

Any changes you make to the Scene will be saved, like a real pedal board. (see page

• 3•2 for details on Autosave vs. Manual Save)

To select a new Scene, you must step on the Scenes switch again, and you’ll see the

•

12 Scene names you started with. Repeat the steps above for new selections.

Latch Scene Mode

In Latch Scene mode, the only difference is when you step on the Scenes switch, the 12 Scene names remain in the LCDs. Any Scene you select will be loaded the same way, but you won’t see it’s FX displayed in the LCDs. The advantage to Latch Scene mode is, you’re always only 1 switch away from selecting a new Scene. So you can have 12 completely different setups ready to go, each only 1 switch away. The disadvantage is, you can’t tweak or bypass any of the individual FX. You can only bypass the entire Scene.

Scenes Details

Autosave

Whether you’re in Momentary Scene mode or Latch Scene mode, your choice of Autosave or Manual Save is an important one. In Autosave, any change you make to your Scene is saved automatically. This includes not only the on or off state of the individual FX while your scene is loaded, but also the conﬁguration of the Scene itself.

Let’s load a Factory Scene and see what happens in Autosave mode. Make sure you’re in Autosave and Momentary mode ﬁrst, so you can access the individual FX. To doublecheck, press and hold the Looper Controls switch for a few seconds, to enter Setup mode.

3•2

Look at LCD 3 under ‘Scenes’ and see if

MNL SAVE and LATCH SCENE, change them with Knob 2 and Knob 4.

Now press the Scenes switch and you’ll see all 12 Scene names displayed. Choose Scene 2A, Bridge Of Vibes. Notice the four A switches are lit. That’s because the loaded FX, which are displayed in the LCDs, are loaded in the A locations of all 4 FX Units. You should see U-Vibe, Tube Drive, Plate and Ping Pong displayed.

Play your guitar for a minute on the neck pickup. You’ll hear a Robin Trower/Hendrix type of sound. Step on all 4 C switches now. You’ll see Facial Fuzz, Analog Flange, Rotary

Drum and Tape Echo. It’s a very different sound. Now step on the Scenes switch and select 1C Swamp Thing. You’ll see 3 LCDs lit, because FX Unit 2 is bypassed. Step on the Scenes switch again and go back to 2A, Bridge Of Vibes. It’s lost its Trower U-Vibe sound. That’s because Autosave has saved your changes. Notice all the C switches are lit.

AUTOSAVE and MOMEN SCENE are assigned. If you see

Manual Save

To see how Manual Save differs from Autosave, let’s do a Factory Reset and start over. If you have any special Scenes saved, you can defer this exercise until you back up your

Scenes to computer. Read all about it in Chapter 1, Page 5. Assuming you’re okay to do

a reset, press and hold the Looper Controls switch to enter Setup mode again. This time turn the Model Select Knob under LCD 4 to select Press again to initiate the reset. After it resets, select

Now repeat the same steps you did before. Press the Scene switch, select Scene 2A, then switch on all the C switches to change the sound of Bridge Of Vibes. Step on the Scenes switch again, select Scene 1C, then step on the Scenes switch and select 2A again. Play your guitar. Notice all the A switches are lit this time. Scene 2A did not retain the changes you made. This can be a good thing, especially if you want to return to the exact same sound you originally programmed. In Manual Save mode, every time you select a Scene, it will be recalled exactly the same way, even if you make temporary changes to it.

RST FACT? and press down on the knob.

MNL SAVE under LCD 3.

Scene Setup

With the M13 you can create your own custom Scenes and save them in all 12 Scene locations. Combine this with the fact that you can back up all your Scenes to computer,

and you have an unlimited ability to customize and store your own library of sounds.

When you begin tweaking the FX models and creating combinations you like, you’ll want

to familiarize yourself with Scene Setup mode. This is where you store and name your

custom Scenes. Let’s take it step by step, and you’ll see how easy it is. Once you have a combination of FX you’d like to store, do the following:

•

With your custom Scene ready to be stored, press and hold the Scenes switch.

The switch light will ﬂash, and you’ll see “Select a Scene for Setup” displayed.•

Select the switch for your current Scene, the one you want to save.•

Its name will appear in the center of the LCD. Name it by turning the Model • Select Knob for character, and Knob 2 far right to move to the next character.

*Here’s a tip: press down on the Model Select knob to quickly jump to ‘a’, ‘space’, ‘0’

or ‘A’. It makes it a lot faster to name your Scene.

With your scene named, press its switch again. It will stop ﬂashing.

•

Press the Scenes switch, then select your custom Scene. You’ve just saved it. •

Scenes Details

3•3

Effect Copy

The main purpose of Effect Copy is to enable you to move your current effect, with all its settings intact, to another location, and to save it there with all your edits intact. This can very useful when you’ve been tweaking an effect, and you get it sounding exactly right, but you’d rather have it routed either before or after another effect in your Scene. Effect Copy

makes this extremely easy to do. Here’s how:

•

Set up the Effect you want to copy, with all parameters adjusted to your liking.

Press down on the Select knob of the source FX Unit - its LCD will begin ﬂashing.•

Press the foot switch of the destination location you’d like to use. •

The LCD will stop ﬂashing, indicating the Effect Copy was successful. •

Your source effect will now be stored in the destination location, with all your settings intact. You can also use Effect Copy to simply re-arrange your existing FX in a Scene. Or experiment with duplicates of a particular sound you’ve created in the same Scene, for an extreme or unique musical effect.

lo o p e r de t A i l S

The Looper in the M13 is similar to the looper in the DL4 Stompbox Modeler. It gives you up to 30 seconds of mono recording time at normal speed, or 60 seconds at half speed. Keep in mind your loop will play back in mono, even if you’re running stereo FX.

Looper & Live Guitar

When you record and play back a loop, your current Scene will still be active. In fact, while your loop is playing you can select a new Scene at any time by stepping on the Scenes switch, then selecting a Scene as usual.

Looper Details

Since the M13 responds to MIDI messages, you can optionally set up a MIDI control device to control the looper, leaving all 12 of your FX Unit switches dedicated to your M13 effects. This way, you could switch your M13’s four sets of A, B and C effects on or off at

any time and still control Play, Record, Overdub, Half Speed and Reverse functions.

Below is a Reference Table of MIDI CC values for controlling M13 Looper functions via MIDI. For a more comprehensive list of M13 MIDI messages, see Appendix A.

MIDI CC Reference Table : Looper Control

M13 Footswitch MIDI CC# Looper Function

Record/Overdub 50 0 to 63 = Overdub 64 to 127 = Record

You can optionally control Looper EQ, Playback and Overdub Levels with an expression pedal by setting up your heel and toe values and assignments in Setup Mode, as described in Chapter 1, Page 2. Also see Chapter 2 for more expression pedal info.

4•1

Looper Details

Looper Controls

When you engage the Looper Controls switch, the 7 switches in the two bottom rows will control the Looper, enabling you to record and play back a loop while your current Scene

is still active. Here are the details:

4•2

Looper Controls Switch – when you step on this switch it will light up red,

indicating the two bottom rows of footswitches will now control various functions of the Looper. Your current Scene will still be active, and each of the loaded FX in your Scene will be displayed in the four FX Unit LCDs.

Record/Overdub – to record a guitar loop, step on this switch and the M13 will

record up to 30 seconds of whatever you play. Step on it a second time and your recorded loop will begin to play back immediately, with Overdub mode activated (LED will ﬂash).

Overdubbing – once you have a loop recorded, you can layer an overdub on your current loop at any time. Simply play back the loop and step on the Record/Overdub switch. Your new live guitar will be recorded along with your previous guitar track.

Looper Levels – the Playback and Overdub Level of your loop will be determined by the Looper Levels you set in Chapter 1, Page 2. Play Level is the volume of your recorded loop in relation to your live guitar volume. Overdub Level is the level of your

7 8

Looper Details

loop that will be recorded each time the loop cycles in Overdub mode. In other words, if Overdub Level is set at 80%, every time your loop cycles in Overdub mode it will decrease in volume by 20% in relation to your live guitar. For no reduction in volume, set Overdub Level to 100%, but be aware that hot levels may build up and distort.

EQ – your recorded loop will also be affected by the EQ settings you made in Chapter

1, Page 1. If Hi Cut is set to On, your loop will play back with the high end slightly

attenuated. Conversely, if Low Cut is set to On, your loop will play back with the low

end slightly cut. Both Hi Cut and Low Cut can be active or off at the same time.

Play/Stop – this switch simply plays or stops your loop. When in Play mode, you

can step on Record/Overdub at any time to overdub live guitar with your recorded loop.

Half Speed – step on this switch while in Play mode and your loop will play back at

half speed. If you switch it again it will toggle back to normal speed. If you want to record an overdub while your loop is playing back at half speed, simply step on the Record switch and play. If you then switch back to normal speed, your new track will play at double speed, while your original track will play at normal speed, as it was originally recorded.

Reverse – this switch puts your loop into reverse, so it will play backwards. You can

activate Reverse at normal speed or half speed, and you can also record an overdub while Reverse is activated. If you do so, when you exit Reverse your newly recorded track will play backwards, and the original track will play back normally, as it was recorded.

Undo – to undo your most recent take while in Overdub mode, step on the Undo

switch. Your earlier recording will remain intact. Only the last take will be undone. *Note: there’s no way to archive loops in memory. Only the current loop is preserved.

Play Once – when you step on this switch, your loop will play once then stop.

Pre/Post – this switch controls whether your loop will play back pre or post the FX

in your current Scene. If toggled Pre (blue), this means your loop will not pass thru the current FX. If toggled Post (green), your loop will play back with your Scene FX applied.

FX Switches – when the Looper Controls are active, the top row of C switches

will control the on/off state of the four loaded FX in your Scene. Stepping on one of these switches will engage or bypass the Effect in that FX Unit, be it loaded in A, B or C. For example, if your current Scene includes a Tube Drive in FX1-A, stepping on the C switch for FX1 will toggle your Tube Drive on or off. This setup enables you to control all four of your FX while their locations may be hidden under the Looper switches.
