Electronically this guitar effect uses the Fuzz Face configuration of the classic two transistor amplifier but the low parts count and simplicity of this configuration produced many problems in the mass produced versions that were produced and available to the public. The large variations in tone quality from unit to unit, radio pickup and high frequency oscillations, temperature causing tone quality to change all made life very difficult and it was not unusual to have to select from up to 20 units to find a really good one. No two units were the same!

The version that we produce today has eliminated all of these problems and is representative of the best units that Jimi used. PNP Germanium transistors of the exact same type that were used in the early versions are very carefully selected for gain and stability to produce the rich smooth rounded tones that the later version NPN silicon transistors failed to emulate. These are still used by many modern manufacturers in so called vintage Fuzz Face versions. Germanium transistors do not pickup radio or oscillate and a pre-set has been added on the PC card to enable the unit to be optimised at varying temperatures. It is unquestionably the most accurate "Vintage fuzz effect" manufactured today that replicates the sound of the early Hendrix tracks. The Roger Mayer Classic Fuzz has the genuine pedigree and heritage and you can rest assured of having a device designed and built by the man who was there.
