From the post

One for the Fuzzynoise-ophiles. Description of the original:

The Soundwave Breakdown takes the idea of a screaming fuzz pedal and turns it inside out. It uses specially matched transistors turned backwards to get it's bombastic sound. The one knob controls extreme biasing of one of the transistors and the other controls intense filtering. Although this sounds simple the results are perplexing. The combination of allow a vast universe of fuzz | distortion | overdive | buzz | grind | bleeps | synth sounds | harmonies | and soundwave manipulation. The exact positions of the knobs yield completely different sounds for endless great insane fuzz tones.
