“Fantastic sounding fuzz pedal from one of
the great builders, Scotty at Pro Analog. Old school build with no 9-volt adapter (battery only) and no LED. Fuzz is at max level when knob is fully
counter-clockwise. It is also very dynamic at lower fuzz settings. This version has the famous NKT275 germanium
