The Arduino Guitar Pedal is based off this instructables guide by Randy Sarafan

For this project, I built an Arduino-controlled guitar effects pedal. I did so by creating a circuit that uses an op-amp to make a pre-amp to boost the guitar signal as well as invert it. The circuit then utilizes an Arduino to convert the signal to digital, then read the signal and change it depending on which effect is in use and output it back to a second op-amp which inverts the signal back as well as mixes the modified signal with the clean signal. The different effects in the pedal are chosen with a rotary switch that contains multiple voltage dividers which are read by the Arduino and chosen according to which voltage is read. The circuit also contains a bypass switch which allows the user to easily switch between the clean signal and the modified signal.
