Witchfinder

The Witchfinder is a highly modified version of the Boss FZ-2 Hyperfuzz. Compared to the original, the 3 way mode switch has been removed along with the Boost mode. Fuzz 1 and Fuzz 2 have been simplified where instead of a fixed mid-cut there is now an active mid range control with a 3-way center frequency toggle.

The High/Treble and Low/Bass controls are active and are retained from the original design. Each of these controls, along with the Mid control, allows you to either cut or boost the signal depending on where you set the control relative to the upright / noon position.

The fuzz circuit is toggled via a footswitch on the left, while the octave up effect that is inherent to all Superfuzz / Hyperfuzz style designs can be toggled via the footswitch on the right.

Mids - The left most toggle changes the frequency range over which the Mid knob operates: Lower Mids / Standard Mids / Upper Mids. When the Mids toggle is set all the way left and the mid control is set to minimum, the circuit will match the original mid-cut notch.
Mode - The center 2-way toggle switch that changes the texture of the clipping in the circuit from a more glitchy, octave based clipping to a smoother more modern fuzz sounding clipping.
Clipping - The far right 3-way switch which can swap the clipping diodes from the original symmetrical Si diodes to no clipping diodes to Red LEDs.
Clean Blend  - sets the ratio of effected to dry signal on the output of the circuit.
Octave  - mix controls the amount of octave up mixed into the main signal during octave mode.
Boost -  sets a the gain boost level when in non-octave mode.
Fuzz - control sets the amount of fuzz
