More Than a Traditional Multi-effects Pedal

At Sweetwater, we understand the appeal of a traditional stompbox, and the Polyend MESS provides all the convenience of analog stompbox control with the expansive capability of digital effects libraries. Fully equipped with a 16-step grid pad, the MESS, or multi-effect step sequencer, is a real-time sequencer and editor with hands-on controls that encourage exploration and experimentation. You can build and save up to 1,000 presets, from straightforward instrument effects to experimental polyrhythmic patterns that evolve as you play. Set up any of the more than 120 effects in four independent tracks with the ability to stack and manipulate each to your desired parameters. With the Polyend MESS outfitting your rig with finite control and maximum customization, static presets are a thing of the past.

Created for any performance

Polyend crafted more than another multi-effects pedal with the MESS supplying unprecedented levels of programmable, performative sound design to anyone creating music. Whether you’re a guitarist expanding your pedalboard, a synthesist looking for creative new sounds, or a sound designer expanding your control, the MESS offers something to love. This powerhouse effects pedal integrates with virtually any setup, whether you’re running into a DAW or straight to a speaker.

Customizable control

The MESS provides four independent tracks that can each stack, sequence, and control the more than 120 effects, with parameters to control the nuances of each effect. You can choose from analog-style modulation and time-based effects or select one of many innovative spectralizers that supply new uses for granular engines. The best part? Every feature and effect can be adjusted right on the pedal itself with an easy-to-read, full-color display; 16 customizable pads; and Settings, Input level, Preset selection, Macro, Mix, and Tempo adjustment controls.

Effects for every occasion

The MESS opens up a new world of possibilities by blending traditional sound shaping with generative and performance power. You can create sequences for entirely new textures that evolve in time, or switch off sequencing and use MESS as a straightforward multi-effects pedal. Either way, you can access countless sonic possibilities with everything from multimode reverb with five different modes and 25 submodes to granular bursts that transform audio in real time and over 25 submodes of modulation. On top of that, you get multiple variations of other effects, including delays, micro-looping, particle samplers, spectralizers, repitching, and more.

Reviews

Falling in Love…
I was somewhat wary of this pedal due to the lack of any positive reviews anywhere online. I don't buy gear based on YouTube influencers. So, after taking a chance to test drive this pedal, my overall opinion is that it's superb. It's heavy, well built, and the sound quality is on par with Eventides algorithms. The randomization feature is a big plus to generate quick new fx chains mainly to sate boredom and inspire creativity. The midi cc sequencer could use a firmware update, but other than that I'm very satisfied with this multi fx pedal. Take one for a test drive to see if it fits your style. Ahhhhhh.
