WHAM Jammer - Build it!

Here's a cool project for the guitar players out there. The WHAM Jammer is a circuit that connects to a DigiTech Whammy 5 pedal through the Midi port and makes it do things that might be considered....unnatural.

The following video shows you how to quickly build the circuit on a breadboard so you can try it out. I'll get to work on designing a proper enclosed version.

  1. Pretty Cool, It will work with Wahammy 4? (a lot of double u on a short frase)

    1. Hi Claudio. I don't have a 4 so I have no way to test. But I would say no.
