Collin's Lab: Guitar pedal modding with ArduinoMarch 29, 2012

[Collin] from Make made a great hack with Arduino to add a tremolo to his Big Muff Pi

Instead of chaining multiple guitar effects in search of a new sound, I decided to mod just one. Using an Arduino microcontroller board + digi-pot chip (MCP41100), I was able to add a variable gating effect to a fuzz pedal fairly easily. I definitely dig the resulting sounds and a bit of rewiring should reduce the unwanted noise in the output. Switching to the MCP42100 would allow control over a second pot – perhaps the volume control for a tremolo effect.

You can find the “WavePot” sketch I used (including the necessary wiring list) here.
