Like the original Fuzz Face, the core of the FuzzTool Junior© is a dual transistor voltage feedback amplifier. The voltage feedback principle is intended to get more gain from a lower gain transistor, in the Fuzz Face it creates the typical touch sensitive character and dynamic response on the use of the guitar volume knob, the so called “clean up” effect. The FuzzTool Junior© is basically a Fuzz Face extended with features that increase operating flexibility and solve shortcomings of the original design but do not change the original Fuzz Face sound character.

Dallas Arbiter Fuzz Face History
The Fuzz Face is the most famous type of fuzz pedal and has become a legend because of it’s dynamic character. It is developed in 1966 by a company called Dallas Arbiter. The Fuzz Face is known in two configurations (1) the pre 1969 version executed with germanium transistors and (2) the post 1969 silicon transistors based version. They both have a different distinct character; germanium is soft and bluesy, silicon has more gain and sounds more harsh, thus more rock character. Famous guitar players who create(d) their unique sound with a Fuzz Face are: Jimi Hendrix, Steve Ray Vaughan and Billy Gibbons.

Tony Spinner: "With my Les Paul I got a great retro tone like old Z.Z.Top. That cool early Billy Gibbons tone! With the Strat, I got the classic Foxy Lady, Hendrix tone“

Technical Specification

Germanium transistor setup - A matched pair of NOS germanium transistors with the correct gains and leakage current for an optimal sound with good clean up character turning back your guitar volume.
Gain control - control the amount of Fuzz
Continuous variable range control (T.M.F.) - dial in the amount of bass and go from thick fuzz to dynamic distortion
Impedance Conversion Interface (on/off) - converting an active input signal (EMG pickups, Wireless system) to a signal suited for the FuzzTool and thus retaining the character of the effect
The PaulSwitch® - robust true bypass footswitch to switch effect on/off & to avoid tone sucking in bypass operation
Pre warning Battery low indication - giving the opportunity to changeover batteries before the effect stops working
Volume control - adjust the overall output volume of the effect
External power supply - (noise reduced) providing the option to use an external power supply without inducing noise or changing the character of the sound.
Reverse and over voltage protection - to protect the sensitive germanium transistors and keeping the pedal running for many years to come
Radio Frequency Interference (RFI) suppression - avoiding radio signal reception when using high gain setting in combination with turning down guitar volume
