Polyend Endless User-Defined Effects Pedal

The Polyend Endless is a user defined multi-effects stompbox that lets you shape your own sound from the ground up.

Load ready-made effects, describe the sound in your head using Polyend Playground, or dive into open source C++ to build completely unique processors.

With drag and drop effect loading over USB-C, a rugged aluminium enclosure and a customisable magnetic faceplate, Endless is a future-proof creative platform for guitarists, synth users and studio tinkerers alike.

Instead of being locked into a fixed set of algorithms, Endless gives you a constantly expanding library of community-made effects alongside powerful tools to create your own. From wild glitch loopers and granular clouds to classic reverbs and amp sims, you can reconfigure the pedal in minutes to suit each session or gig. It is a single box that can be almost anything you want it to be.

Describe It, Play It

At the heart of Endless is Polyend Playground, a text-based environment that turns your ideas into working effects. Type a description of the sound you want, and Playground generates, tests and compiles the code for you, delivering a ready-to-load file in minutes. You then simply drag and drop that file to the pedal over USB-C. No coding knowledge is required, and a token-based system means there are no subscriptions or ongoing cloud fees to worry about.

Open Source for Deep Tweakers

If you prefer full control, Endless also offers an open source route. Polyend provides a GitHub repository with an SDK and example projects, so anyone with some C++ knowledge, or the desire to learn, can build effects from scratch. You can refine existing ideas, port your favourite algorithms, or design completely new tools that go far beyond standard delays and drives.

Limitless Sonic Experiments

Endless is not restricted to a particular category of effect. Within the scope of the hardware, you can create or load anything from reverbs, amp simulations and loopers to experimental processors that respond to your playing in unusual ways. Existing examples include micro-looping arpeggiators, lo-fi tape delays, VHS-style degradation, granular memory clouds, multiband drives and glitchy loop slicers. If you can describe it or code it, Endless can host it.

Built to Live on Your Pedalboard

The hardware is designed to be as robust and flexible as the software. A compact machined aluminium enclosure and knobs are ready for stage use, while the magnetic faceplate system lets you swap designs or write your own control labels. Dual footswitches, three multifunction knobs, a multicolour LED indicator and configurable stereo or mono I/O make Endless easy to integrate into guitar, synth or studio rigs.

Key Features

• Code-free effect creation with Playground - Use Polyend Playground to describe the sound you want in plain text and receive a compiled, ready-to-load effect in minutes. This lets you focus on musical ideas rather than programming, while still accessing highly customised, one-off processors tailored to your playing.
• Open source C++ development platform - For those who want deeper control, Endless offers a GitHub-hosted SDK and examples so you can write your own C++ effects. This turns the pedal into a flexible development platform, ideal for experimenting with new algorithms or building signature sounds that no other pedal can replicate.
• Expandable community effect library - Endless effects are designed to be freely shared, with over 50 custom effects available at launch and more added daily. You can download and swap effects as often as you like, giving you a constantly evolving toolbox of creative sounds without additional cost for community creations.
• Rugged, customisable pedalboard hardware - A machined aluminium enclosure, magnetic swappable faceplate, stereo 48 kHz / 24-bit audio engine and low-noise analogue preamp make Endless ready for serious live and studio use. Dual stompswitches, three multifunction knobs and configurable I/O ensure it fits neatly into a wide range of setups.
