Troubleshooting & Service

A: You can perform a factory reset by entering the Setup screen and turning the Model Select knob on FX UNIT 4 until the corresponding parameter displays ‘RST FACT?’ You can then press down on the Model Select Knob twice to reset the unit. You can also re-install the flash memory to return the M13 to factory settings.


Q: Does Line 6 M13 Stompbox Modeler include guitar amp or cab modeling?
A: Nope. Just stompboxes.


Q: Will the looper still work while I'm changing sounds and scenes?
A: Absolutely. Once you have captured your looped creation, leave it repeating and go back to using any of the effects.


Q: Where's the tuner?
A: Press and hold down the TAP TEMPO button to activate the tuner. When activated, the tuner shows up in the LCD. By default, once the tuner is activated all signals are muted.


Q: What is a "Scene"?
A: A "scene" is a pedal board arrangement on your Line 6 M13 Stompbox Modeler with 12 available effects, up to 4 at once.


Q: How does Latch Scene mode work?
A: You can switch between the different Scenes (presets) of the M13 with a single button press. You must first go into the M13’s SETUP menu (hold the Looper Controls button for a few seconds), and in the FX3 screen, turn the middle knob in the bottom row clockwise to change the SCENE mode to ‘LATCH’. Now exit the SETUP menu (hit Looper Controls again) and press the SCENES switch to view the different Scenes of effects. Now, when you press on each of the Scenes footswitches, it will call up the Scene, but you will remain in the Scenes view allowing you to change to a different Scene of effects with a single button press.


Q: How many scenes are there and how do I access them?
A: With the 2.01 update, you can create and save up to 12 different scenes in one Scene Folder. With 4 Scene Folders, you get 48 total scenes on the M13! Press the scenes button to access the scenes and turn the MODEL SELECT knob on FX Unit 1 to access the additional folders.


Q: Can I backup my scenes to my computer?
A: You can backup your scenes via MIDI. Check out the M13 Scene Backup document.


Q: Where can I get the factory scenes for my M13?
A: You can regain the factory scenes on the M13 following the reset procedure described above, or you can download the individual scenes from the Institute of Noise website.


Q: Which expression pedals can I use with the M13?
A: We recommend using the Line 6 EX-1 or the Mission Engineering EP1-L6 expression pedals. You can also use any other expression pedal containing a 10k Ohm Potentiometer. Expression pedals allow you to change stompbox controls using your feet so you can adjust the sound while you play. On the fly, you can modify the length of your delay time, dial up the reverb mix, or change the depth of your tremolo.


Q: One of my LCD screen's color appears to be different than the other LCD's that have the same model family selected. Can I adjust the color to match the other displays (i.e. I have 4 cascading Delay models and screen #2 appears to be not quite as "green" as the other 3)?
A: Yes. Power off the unit. Hold down the "Model Select" knob of LCD screen #3. Power on the unit. You can now adjust the relative color of each LCD display screen relative to the other ones.
