GoKawiilOpen-source pedal runs full Neural Amp Modeler captures on ESP32-S3
A developer built CoyoPedal, a standalone guitar amp and effects unit powered by the Waveshare ESP32-S3-Touch-AMOLED-2.06 board, capable of running full-size Neural Amp Modeler A2 captures in real time. The device uses a class-compliant USB audio interface, a touchscreen UI compiled from TSX to native C++, and also runs identically on a bare ESP32-S3 module or as a WebAssembly build playable in a browser.
GoKawiil's interpretation of the reporting above, not reported fact.
Running a 23-layer WaveNet neural amp model in real time on a low-cost microcontroller, without a desktop converter or cloud processing, suggests hobbyist hardware is closing in on capabilities once reserved for dedicated DSP amp modelers. Offering the same firmware across a touchscreen pedal, a bare board, and a browser-based WebAssembly demo could lower the barrier for musicians and developers to experiment with neural amp modeling without buying specialized gear.
- CoyoPedal runs full-size Neural Amp Modeler A2 captures directly on an ESP32-S3 chip in real time.
- The same firmware works on a touchscreen pedal, a bare ESP32-S3 board, or as a browser-based WebAssembly app.
- Users can load their own .nam capture files via microSD or browser folder, with on-device parsing and no desktop converter needed.
Waveshare ESP32-S3-Touch-AMOLED-2.06 — This is the exact board CoyoPedal is built on, featuring a touchscreen AMOLED display and ESP32-S3 power needed to run real-time neural amp modeling and effects. If you want to build your own standalone guitar pedal with a slick touch UI, this is the core hardware to start with.
