The Octapussy is essentially, an octave-up fuzz in the tradition of the Octavia. But it’s not a clone of that circuit! Nope, it’s an original circuit utilizing 3 silicon transistors and two diodes that takes the tradition to the next level! The preamp section is custom voiced to give you an extremely dynamic playing response. You’ll get those famous high-octave lead tones up high on the guitar neck but you’ll also get an amazing array of fuzz tones anywhere else on the neck - just by how you play it and how your GUITAR’s volume, tone, and pickup selector is set.
The ATTN (Attenuation) control should normally be set full counter-clockwise. For best tone and response, only attenuate when you’ve got the Gain and Body knobs really cranking and need to reduce the output some.
The GAIN control increases the gain for more fuzz, harmonics, and uppermidrange frequency boost. It is voiced to be usable throughout its range from minimum all the way to maximum.
The BODY control increases the bass response as well as making the octave more prominent. Like the Gain knob, it also increases output and harmonic content. Technically, it is a negative-feedback loop with variable frequency response. But let’s not dwell on technicals.... this is another MOAR knob! To get the best feel for what this knob does, set it at minimum and then slowly bring it up as you thump the low E string on your guitar. You’ll hear (and feel!) the low end thump increase as you turn up the Body.
