2011 Faustone Fuzz Unit

2011 Faustone Fuzz Unit in very good condition, serial number 62, made in July 2011.  Our tech cleaned internally, inspected connections and component values and tested with a fresh 9volt battery.

From Faustone:

The Faustone Fuzz Unit is a replica of the rare Barnes and Mullins (B&M) Champion Fuzz Unit. The original pedals were built by Colorsound in London in the late 70s. Rebranded under many names —B&M, CMI, G.B., Pro’Traffic— electronically the circuit was the British cousin of the Electro Harmonix Big Muff, and —allegedly— it was featured on “A Girl Like You”, the Edwyn Collins hit single.

This Faustone version is based on my April 1977 original which was carefully dissected, studied and re-assembled. The circuit on mine is a tad different from the available Internet schematic, and features Zetex brand transistors instead of the ubiquitous BC184Cs.

The circuit is basically a clone of a Big Muff minus the fourth transistor position. In the Fuzz Unit, two ZTX383C transistors —with a gain of around 600— occupy the two first positions (Q1 and Q2). A lower gain transistor is used for Q3 —ZTX382B, gain of 150— which in my opinion is the key to achieving the characteristic musical flute-like sound of the original pedal.

Very much like other Colorsound pedals before, these late 70s “Tonebenders” were built into Wah-Wah enclosures, hence the shape and dimensions of the boxes. I cloned the box but I made it sturdier because mine is a bit dented after 30+ years of use. I had it powder-coated in bright orange and cloned the original silkscreening too.
