Guitar amp and effects pedal built on the Waveshare ESP32-S3-Touch-AMOLED-2.06
A unique guitar amp and effects pedal has been built using the Waveshare ESP32-S3-Touch-AMOLED-2.06. This device utilizes the full-size Neural Amp Modeler A2, which captures audio in real-time on the ESP32-S3, and drives a class-compliant USB audio interface as a USB host. The touchscreen interface is written in TSX and compiled to native C++, with no JavaScript engine on the device.
The screen is housed on a separate board, while the same firmware can be compiled to WebAssembly for a minimalist version without a panel. The firmware can be run on any board equipped with an ESP32-S3, 8 MB of PSRAM, and a USB port. The pedal features an AMOLED display, which is the reference for all presets and captures. A bare board functions identically, with firmware configured over the maintenance API.
Users can browse, edit, and save presets, as well as select and play factory captures from the SD card. The device supports 48 kHz, eight-channel NAM A2 WaveNets and can accept prepared .namb files. The pedal boots engaged with a remembered preset or the first preset, Silver Lining, if no selection has been saved. The firmware includes a full VoLum library, which can be cloned and installed on the device. The device supports OTA updates and can be controlled via a maintenance mode and remote tools.
