I made this out of stuff from my junk box/pile. The main circuit is from a Radio Shack desktop toy called “The Revenger”, complete with Laser, Machine Gun, & Bomb sound effects. I may have to record another video using the Dub Box Delay so you can hear the true LoFi reggae glory. Simple pitch bend on the timing resistor also attached to touch points, one other touch point going to a leg of the capacitor.
