We’re excited to announce Endless. It is a new class of customizable effect pedal that can load a library of available effects, code new ones, or describe a sound in Playground (beta) and get a ready-to-play effect with no coding required. Endless pairs this flexibility with a custom-machined aluminum enclosure, magnetic, swappable faceplate, and a stereo 48 kHz / 24-bit audio path.
What is Endless? A Path to Open Effect Creation
With two ways to create, Endless is both an open source device and the first pedal to generate effects from your descriptions. Endless can create classic effects, from reverbs, amp sims, loopers, drives, or become something completely new. Swap sounds in seconds over USB-C and play.
Two Paths to your Effects
- Playground (beta) — A text-based effect builder that turns natural-language descriptions into compiled, ready-to-load effects. Describe an idea, download the file, and drop it into the pedal. Play it, suggest tweaks, ask for improvements, and get results without coding.
- Develop your own — Start with Polyend’s GitHub SDK and examples and write your own DSP. Build and copy over USB-C, play.
What can you build?
Endless doesn’t place limits on what you can build. Create and share effects that can’t be found in another pedal, and access an effect library that is growing daily. Available effects include:
- Multidrive — multiband drive with selectable bands and multiple drive modes.
- Tessera — transforms a signal into micro-looping arpeggios.
- Tape Scanner — warm, gritty, lo-fi tape delay.
- VHS Lo-Fi — VHS emulation from “fresh” to “dusty.”
- Memory Cloud — a field of grains that can be reversed, randomized, and morphed from delay to reverb.
- 65’ Sparkle — amp simulation tuned for edge-of-breakup sweetness.
- Glitch Loop — records a loop, then slices it into glitchy pieces on playback.
- Arp — an arpeggiating pitch shifter with multiple playback modes.
Community effects are free to download, and new effects are added daily. You own what you create; sharing is optional. A token system applies only when generating new effects in the Playground. No subscriptions. No cloud fees. Playground access requires a registered Endless.
Unique Hardware Built to Customize
Custom hardware was created to reflect the internal flexibility of Endless. Encased in a custom machined-aluminum enclosure with aluminum knobs, a one-of-a-kind swappable faceplate system is used. A blank plate ships at launch, with more designs and DIY specs available. Two footswitches handle control (right = on/bypass; the left is freely assignable on tap or hold), with a multicolor LED that changes state based on the left switch’s short/long latch. The three front-panel knobs pull double duty—hold On to access analog preamp level, master output, and wet/dry mix—and the configurable I/O lets you switch the pedal between stereo, mono, or mono-to-stereo to fit any rig.
Price & availability
Endless is available for preorder now at $299 / €299. Shipping starts February 22, 2026. New units include a blank faceplate and $20 in Playground tokens. Playground (beta) access is available to registered Endless owners.
See it in LA
Check out Endless in person in LA at either NAMM booth 5249 or at Buchla and Friends.
I’ll try and answer questions here - but we are at NAMM right now so may be slow to respond.
I am waiting on sound samples of things that are unique that can’t already be done before I decide if it’s something I need / want. So I gotta be patient and wait until they get in the hands of people.
