Hey, I'm working on a guitar pedal. It is a multi-effects pedal based on a Pi Pico:

It will connect to a VGA monitor and have cool visual effects to go along the with the playing. So far I have implemented:
Delay, Room Echoes, Low Pass, High Pass, Bandpass, Wah Pedal, Phaser, Flanger, Distortion, Overdrive, and Ring Modulator.
The pedal can be programmed so that several effects are cascaded.
