The exact positions of the knobs yield completely different sounds, ranging from fuzz, buzz, and grind to bleeps, synth sounds, etc. A vast universe of gnarliness is yours. Be forewarned, it's only grizzled psycho fuzz all the time. The Soundwave Breakdown takes the idea of a screaming fuzz pedal and turns it inside out, utilizing specially matched transistors turned backwards to get its bombastic sound. • MFSKU Soundwave Breakdown • UPC 720260152393
