A standalone guitar amp and effects pedal built on the Waveshare ESP32-S3-Touch-AMOLED-2.06 . It runs full-size Neural Amp Modeler A2 captures in real time on the ESP32-S3, drives a class-compliant USB audio interface as a USB host, and has a touchscreen UI written in TSX that is compiled to native C++ — there is no JavaScript engine on the device.

The screen is one board's worth of it rather than the pedal itself: the same firmware builds for a bare ESP32-S3 module with no panel at all, where the amp, the effects and the presets are the same and the BOOT button is the footswitch.

Play it in your browser → The same firmware compiled to WebAssembly: the same UI, the same DSP, the same neural amp model, playing your guitar through an audio interface. No board required to try it, and nothing to install.
