wow, this is amazing.
A guitar pedalboard that grows with your ideas. Snap on another board and make room for more sound!
Built on Espressif’s ESP-Mosaico, this setup starts with guitar effects and amp modelling on a single device. Add more boards and the app spreads the signal chain across them. With four, you can run two amp models in parallel and blend their tones.
GEA brings the touchscreen interface to life with TypeScript, JSX and CSS compiled into native code. The boards share audio wirelessly over ESP-NOW, while you tap through effects and explore different presets.
