What do you do with that little plastic axe once you’ve had your fill of Guitar Hero? Turn it into a real instrument, of course. Arizona maker Justin Bread added just enough components to convert his into a simple square wave synth:
The oscillator is based on the LM386 amplifier I. C. and generates a square wave tone. The whammy bar on the controller is functional and alters the tone when handled. It’s signal is sent to an output jack when the strum bar is triggered and runs on a 9 volt battery.
