Gravity Wave

This is a PCB from the Madbean’s Etchers Paradise. Its a Earthquaker Sea Machine work a like. This thing can go from subtle to wacky chorus in a quarter of a turn. I played with it for about an hour and found all kinds of great sounds from this thing. I will definetly box this up at some point.
