F
FUZZ OCTAVE
X Type:
Build Level: Beginner
Based On: Univox® Super Fuzz™
The Bonesaw is a faithful adaption of the ever-popular Univox® SuperFuzz™. It produces thick
fuzz with a pronounced analog octave-up. This is a gnarly sounding circuit and fit for any guitar
player who likes chaos now and then. Like most octave-up fuzz, when doing double stop bends a
third note is produced that dive-bombs with the strings.
EXP: Fuzz/Gain control
BAL: Ouput volume.
TONE: Down position is "normal". Up position is heavily scooped.
SCOOP: This dip switch changes the frequency center of the Tone control in the up position.
OCT: This trimmer changes the tonality of the octave up sound. See Notes.
