An octave-up fuzz modelled on the sixties silicon circuit Hendrix made famous, all analogue, with two knobs: Volume for output level and Boost for the amount of fuzz. Play up past the 12th fret on the neck pickup with the fuzz backed off and you get the chirping upper octave it is known for. True bypass. Quarter-inch in and out, 200 kilohm input. Runs on a 9 V battery or a centre-negative 9 V supply and draws only 10 mA. Case 140 x 80 x 70 mm, 520 g.
