In this interesting headphone hack, you’ll “be attaching a 1/4″ mono jack to the microphone input pads on the controller PCB to allow connection and recording of just about anything that uses that type of jack, including guitars, bases, microphones, etc.” Video after the break.

The original idea was much more complicated than this, but I decided to try this out first as it would be easier for the majority of people who wanted to try it.
