MESS Multi-Effect Step Sequencer

MESS turns a simple guitar line into something bigger. Atmospheres, pulses, textures you didn’t expect — the kind of sounds that keep you curious and make you want to play more.

Main features

4 Effect Tracks

Stack up to four effects at once. Each one moves differently, so the sound keeps shifting and surprising you.

125 Stereo Effects

Some effects sound safe, others sound like you’ve broken the rules. With 125 to choose from, MESS makes sure you never run out of either.

Why Sequence?

Sequencing makes effects come alive. Instead of one static sound, you get movement, rhythm, and textures that keep evolving as you play.

Image
Extravagant or Traditional

One moment it’s your trusty pedalboard. The next is a box of sonic mischief. MESS switches between the familiar and the unexpected with a single tap.

Image
Reverbs & Delays

Reverb and delay aren’t just effects — they’re the room you play in. With MESS you can shrink it to a closet, stretch it to a cathedral, or turn it into a hall of mirrors. Then make the room itself dance in time.

Image
Granular & Glitch

Granular and Glitch don’t tidy up your sound — they break it, bend it, and scatter it. But that’s often where the magic lives: in the pieces that shouldn’t quite fit.

Image
Shapers, Drives & Filters

Sometimes you want a touch of warmth, sometimes you want to burn the whole thing down. From gentle drive to brutal bitcrush, MESS lets you decide how polite your sound should be.

Image
Pitch Shift & Spectralize

One note doesn’t have to stay one note. Shift it, split it, smear it across the spectrum. Suddenly a single string feels like an orchestra.

Image
Slicers & Microloopers

Turn moments into patterns. Chop a sound into tiny loops, bend the pitch, or drop it out like tape grinding to a halt. Add a touch of chance and MESS throws in stutters and repeats you couldn’t have planned — the sweet spot between control and chaos.

Everything changes

Most pedals give you the same effect over and over. MESS doesn’t. Every sequence shifts the rules a little, so your sound keeps moving instead of looping in circles. Sometimes it’s gentle, sometimes it’s chaotic — glitches, stutters, repeats that feel alive. It’s not just an effect, it’s a rhythm engine for guitars, drum machines, synths, or whatever you plug in.

Drone and Dissolve

MESS is instant atmosphere. Layer effects in any order, even without the sequencer running. From subtle warmth to fuzzed-out chaos, it shapes your sound into something richer, stranger, or just more alive.

Mold the Sound

Think of MESS as clay for sound. You can mold it, stretch it, or let it slowly collapse into shape. Pitch-shifted reverbs, sliced loops, drifting delays — they all combine into evolving textures you won’t find anywhere else.

Happy Accidents

Sometimes the best ideas are the ones you didn’t plan. MESS gives you 150 presets to spark instant creativity, plus room for a thousand of your own. One knob per function keeps things simple, and the 16-step grid lets you build sequences fast. Less fiddling, more playing.
