A blend of silicon and germanium transistors pushed to near melting point, creates a variety of intense and powerful fuzz tones, from 60s psychedelic garage fuzz to extreme uncompromising stoner growl. The health knob has a dramatic effect on the way this pedal acts and sounds. Fully clockwise, the fuzz is at its best shape - aggressive , jumpy and loud. Turn the health down and make it sweat - this fuzz sounds crazier as it struggle to fight back. Finally it submits and delivers a sweet gargle, making your guitar sound like a disrupted brass instrument.
