However, in a feedback loop, which is what the sound clip is of, this thing get's quite crazy. Lots of pulses, squeals and clicks. The up and down position of the three-way toggle are very similar in sound, but flipping it quickly from up to down gives a cool glitching effect. I was going to make the third position engage completely different sound, but I decided not to considering most circuit-bent devices I've seen aren't wired to do that. All of the knobs work and alter the sound except for the level knob which is always up. In a loop, the pedal works on and off, but doesn't do much when off.
