Polyend has launched Endless, a customisable effect pedal for tweakers and experimentalists who want to create their own effects. Taking FX pedal customisation into new AI territory with code and beyond!

Polyend Endless
Polyend has just announced Endless, a highly customisable effect pedal that lets you change how it sounds whenever you want. Instead of being stuck with one effect, you can load new ones from a library or even create your own.
Three Ways to Play
Choose from a library of existing effects, write your own code, or use the Playground (beta) tool to describe a sound and let the pedal generate it for you—no coding needed. The hardware delivers what is described as professional-grade sound with a stereo 48 kHz/24-bit audio path. Which, I’m guessing, will really open up the possibilities of the effect you can create, as stereo is always more fun.
Building Your Own
It is the first device of its kind to generate effects from simple text descriptions or through open-source coding. Whether you need a classic reverb, an amp simulator, a looper, or a unique distortion, you can swap sounds in seconds via USB-C.
Endless is based on a Real-Time DSP Core 720 MHz ARM Cortex-M7, making it fairly powerful for an effects pedal.
Playground
AI comes into play. Because via a special website called Playground, you can create your very own custom effect using prompts and load it onto the pedal. After creating an effect and loading it onto the pedal, you can further fine-tune it in the Playground environment online.
There’s a kind of credit system here. Each effect prompt costs one credit, but then the created effect belongs to you. Every new owner starts with 20 tokens.
Text-to-Effect
This is a natural-language builder that requires zero coding. Simply describe the sound you want (e.g., “a dreamy, lo-fi reverb with a bit of grit”), download the generated file, and drop it onto the pedal. If it’s not quite right, suggest tweaks or improvements until it’s perfect.
Open Source
For those who want total control, Endless is an open-source platform (yay!). Using Polyend’s GitHub SDK and provided examples, you can write your own custom DSP (Digital Signal Processing) code, build it, and upload it directly via USB-C.
Limitless FX?
Endless is potentially a limitless platform for sound. Their existing library already includes a wide range of high-quality sounds, as listed below.
- Multidrive: A multiband distortion with various drive modes.
- Tessera: Turns your signal into micro-looping arpeggios.
- Tape Scanner: A warm, lo-fi tape delay with plenty of grit.
- VHS Lo-Fi: Emulates the sound of VHS tapes, from “new” to “worn out.”
- Memory Cloud: A granular effect that morphs between delay and reverb.
- 65’ Sparkle: An amp sim tuned for that perfect “edge-of-breakup” tone.
- Glitch Loop: Captures a loop and slices it into rhythmic, glitchy pieces.
- Arp: A pitch shifter that creates arpeggios with multiple playback modes.
Hardware & Customisation
Endless’ hardware is designed to be as flexible as its software. It features a premium, machined-aluminum build with a unique, customisable look and versatile controls.
Magnetic Swappable Faceplates
The pedal features a one-of-a-kind magnetic swappable faceplate system. It ships with a blank plate, but you can swap it for different designs or even use DIY specs to create your own.
They already have many premade plates of these available for purchase online from their store.
Footswitches
It has two switches: the Right Switch is dedicated to Standard On/Bypass. Whereas the Left Switch is completely assignable. You can, for example, program it to do different things when you “tap” versus “hold.” A multicoloured LED changes colour to show exactly what the left switch is doing.
The inputs and outputs are configurable, allowing you to run the pedal in Mono, Stereo, or Mono-to-Stereo.
It supports TRS expression pedals and will run on any 9–12 V DC power supply with center-negative or center-positive polarity (200 mA required).
Hidden Functions
The three main knobs do double duty. By holding the On switch, you can instantly adjust the analog preamp level, master output, and wet/dry mix.
Preorder & Pricing
You can preorder Endless now for $299 / €299, with shipping scheduled to begin on February 22, 2026. Each new unit comes with a customisable blank faceplate and $20 in Playground tokens to get you started.
Available at Thomann, priced €299
Once you register your device, you will also gain full access to the Playground (beta) effect builder.
