Polyend’s reputation for out-there, beautifully designed gear continues with the debut of MESS — a step-sequenced multi-effects pedal that looks like it belongs just as much on a synth rig as it does on a pedalboard. Announced at Superbooth 2025, it brings everything from lush reverbs to glitchy repeats into a four-track sequencer format. We’re here for it.
Key Features
- Four fully assignable stereo effect tracks
- 125+ effect types: delays, reverbs, granular, glitch, shaping and more
- 16-step per-track sequencing with chance and probability options
- Over 200 presets, with storage for 1000 user patches
- Stereo I/O, MIDI in/out, and USB-C for DAWless or hybrid rigs
Step-Sequenced Mayhem
MESS isn’t your standard stompbox. It gives you four simultaneous effect lanes, and each one can be assigned any of the 125+ effects onboard — so you can run a granular freeze into a spectral reverb, slap a bitcrusher on top, and let it all repeat in a 16-step loop. Or just dial in a classic delay-reverb-chorus chain and be on your way.
Each track’s step sequence can vary in length, tempo division, and probability, meaning it’s great for setting up generative FX patterns that shift and evolve. Everything syncs, or doesn’t, depending on what vibe you’re after. You can sequence things like filter cutoff, delay feedback, or glitch speed per step. It’s a great way to make effects feel like an instrument rather than an afterthought.
Reverb, Delay, and Beyond
There’s a lot going on under the hood: seven core reverb types with all the modulated shimmer and ambient wash you could want, plus multi-mode delays from crunchy analog to clean digital. Things really start to get wild with the granular and glitch engines — which can smear, fragment, and microloop your sound across synced steps.
Effects like pitch shifting, spectral processing, and tape-style loopers give it a sound-mangler vibe too. It’s the kind of box you can use to completely resample your synth or guitar sound, layer textures, or just obliterate clean inputs in the most musical way possible.
Use It With or Without the Sequencer
While the sequencing is what sets MESS apart, all of the effects can be activated without the step-grid running. So if you want a killer delay and reverb chain, no problem — tap in tempo, stomp on the effect, and go. And with MIDI I/O and USB-C onboard, it plays nice with both traditional pedalboards and studio rigs.
There are over 200 presets to get you started, and the interface is super friendly: dedicated knobs for each function, a simple 16-step pad grid, and clear feedback for what you’re tweaking.
Polyend MESS is available for preorder now, with shipping set to begin June 30.

We reckon MESS will appeal to any musician looking to go deeper with FX — especially if your setup’s already sequencer-heavy and you’ve ever wished your delay could be as rhythmic as your beats.
