I modified a cassette player to play like a synth - Pt.1 

Here is the first mock-up of an instrument I'm building. A cassette player that is controlled by a few variable speed potentiometers. It's a speed-control mod that allows the cassette tape to be played like a warbly, tune-able synth sort of thing. I'll post more videos as I continue to build it.
