Thought I'd share this demo video I made of how many different clipping diodes sound throught the same circuit. The clippers are all held in a separate box with a 1/4" stereo plug that can be mated to a 1/4" stereo jack wired to the circuit. The video features the One Transistor Overdrive/Distortion circuit based on the Electra circuit.
