The GOAT of multi-effects pedals. Still highly relevant and hard to beat in 2026. Watch the video below if you’re not familiar.

If you are familiar, this is a great used model with all functions tested. Power supply included per buyer’s request at no additional cost.

Use multiple effects, the way you want them

M9 Stompbox Modeler is three effects units in one! Three effects can be used simultaneously, with three more at the ready. With 100 percent control over effect type and arrangement, you're free to use one effect at a time, arrange them into tried-and-true combinations, or create your own original blends. Different stompbox arrangements, or "scenes," can be created for each of your gigs-one for your metal band, one for your punk band, one for your Top 40 gig - you get the picture. Create and save up to six scenes (scenes can be backed up to your computer via MIDI in/out).

Classic stompbox control

M9 Stompbox Modeler is easy to use, just like a classic stompbox. Tweak your tones on the fly using the dedicated knobs. No menus, no saving, no hassles-just turn the knobs and you're done. And your settings remain when you power down! The bright LCD shows parameter names/values and the built-in chromatic tuner. (When activated, the tuner mutes the output signal.)

Loop it

The M9's built-in 28-second looper delivers extended, in-the-moment looping and unlimited sonic possibilities. Looping has never been easier with dedicated footswitches for all looper controls: Record/Overdub, Play/Stop, Play Once, Undo/Redo, Half Speed and Reverse (the looper and the effects units can be used simultaneously).

The I/O options you need

M9 Stompbox Modeler is ready for anything with its full arsenal of ins and outs. 1/4" mono/stereo inputs and outputs (with True Analog Bypass or DSP Bypass) let you put M9 Stompbox Modeler before, after or in between your other pedals. Connect a pair of expression pedals to the two 1/4" expression pedal jacks to morph smoothly between tones and control the new Pitch Glide and Wah models. MIDI in/out, which is perfect for backing up your "scenes," also makes M9 Stompbox Modeler compatible with many popular MIDI control systems.
