Deadbird is a passionate guitar player and has “right” hands for electronics. This is all you need to avoid high expenses on equipment. So he wanted to squeeze out some more from his Whammy 4 guitar pedal by stuffing someMIDI commands to it. Of course one way to do this is to use aMIDI controller that costs more than … Arduino.

So he hooked an Arduino to pedal MIDI port and wrote some test routines that allowed him to get desired effects. This is still a prototype but he’s working on better version where everything is going to be packet in to aluminum case and have more cool features.
