Noise 567

I’ve been interested in ring modulators for a while now. After failing to make a simple passive one work, I stumbled upon Christian P. Hemmo’s Noise 567. It looked far to simple to be true, but heck it worked like a charm. This little circuit started spitting out noise in no time at all. Higher notes will even be pitch bent. Very cool circuit. Video above is me doing my best imitation of Gearmandude in the demo of the guitar pedal version I built.
