This pedal chassis and other printable components can be used to create any variable resistor (potentiometer) based audio pedal. My primary objective was to just create an expression pedal that could be used in conjunction with my Midi BLE Pedal, but I thought I'd add a few more ideas for a volume, or tone pedal.

Enjoy!
