Something that the Befaco Rampage synth module notes as a possible patch is to connect a guitar (through a line level converter) into one of the inputs, and connect the amp to the Rising output. The Rampage detects whether a voltage is rising or falling, with the two Rising and Falling outputs going hot as a result.
The audio out is a squarewave, with the high portions where the guitar signal is rising, and low everywhere else. It sounds harsh as hell.
Anyone else tried this?

There's the webpage about the module. If you decide to DIY it, get the kit (it uses funny LEDs, and sliders that are a bugger to get), and be VERY careful with component positioning. Some people populate the polystyrene caps on the back of the board.
