This AI guitar pedal let me roll my own effects

I’m not sure anyone was really asking for an AI guitar pedal. But it was inevitable that someone would build one. One of the first to take the plunge is Polyend, a well-respected music gear maker with a reputation for building niche, idiosyncratic devices. The company has built grooveboxes around old-school trackers and a multi-effect pedal that you can step sequence. So there was at least some hope that if anyone could do an AI effect pedal right, it would be Polyend. This AI guitar pedal let me roll my own effects I don’t hate Polyend’s Endless, but I’m not putting it on my pedalboard. If you buy something from a Verge link, Vox Media may earn a commission. See our ethics statement. Polyend’s Endless is a $299 programmable guitar pedal running an ARM processor. It’s paired with Playground, a number of interconnected AI agents that turn any text prompt into a functioning guitar effect. If you have an idea, you don’t have to hope that someone’s already built that pedal; you can simply prompt it. Maybe there’s a specific combination of effects that you’ve always wanted, but no company sells it because there’s no demand for a combination ring modulator / auto-wah. I’m not convinced this is what guitarists are yearning for, but it’s a well-intentioned first attempt to marry an effect pedal to an LLM. Polyend Endless The Good - Dozens of free effects - User-friendly AI Playground - Reasonably priced - Honest effort at “ethical” AI The Bad - Iterating and testing effects takes time - Firmware quirks - Other custom effects pedals offer more control To be clear, the AI isn’t actually in the pedal. Instead, Polyend trained a custom LLM to code effects you can then load onto the pedal. You can also build effects yourself in C++, but most people will either download existing free Plates (as Polyend calls the effects) from the community site or prompt them in Playground. You can also pay $20 for a physical faceplate to pair with a downloaded effect. Right now, the Plates gallery is home to about 60 effects, mostly developed by Polyend. They cover everything from simple saturators to tape loop simulators and guitar synths. There are even self-playing drum machines. Some of my favorites include Grunt (a lo-fi octave down effect), the Infinite Hall reverb, and Tessera (granular pitch-shifting reverb). There’s also Stardust, an enormous-sounding granular delay, reverb, and tremolo combination that would be hard to find elsewhere. Polyend is opening up the gallery to third-party contributions as well, so you could whip up an effect in Playground and submit it for consideration. Playground is the reason most people will be eyeing Endless. It’s a web frontend for several AI agents working in tandem, trained on Polyend’s own effects library. The various AI components interpret prompts, select effect algorithms, generate code based on those building blocks, and then validate that code to ensure it will run properly without blowing out your eardrums.
