Limited Blue Swirl Finish

AC128 ARBITRARY FUZZ

This is an old-recipe, classic germanium fuzz, built to end your Fuzz Face search. New-old-stock European AC128 transistors are used, housed on a turret circuit board.

The Roger Mayer Hendrix mods have been implemented, which make better use of AC128 transistors. These mods notably output higher gain than the standard fuzz face, and cleans up neater with the volume knob rolled back. The FUZZ knob has an extended range, and improved sweep.

There is no internal battery space. A battery may be used by means of an external adapter.

This pedal should be placed first in the signal chain to voice correctly, connected directly to the instrument, and before any buffered pedals.

The aluminium can capacitors are ridiculously oversized for their rated voltages. They are audio rated for very low ESR.

This circuit uses PNP type transistors. The power supply input is the industry standard 9V type with negative centre. However, for purity of sound; the case is positively-grounded, and as such cannot share a power supply with other pedals unless the supply has isolated outputs.

The transistors used are cherry-picked for suitability from my collection which I have saved for many years, and as such are limited in availability. First in, best dressed. Germanium transistors are temperature sensitive, and will perform differently according to the ambient temperature.

A Carling DPDT footswitch is used for the familiar under-foot haptic clunk. Components used may vary to those shown in the photo. Photos are shown as a general guide for construction and components quality.

There is also a listing option for ' A-stock' hydro swirl paint finish. Each is unique, and some more interesting than others. Website purchases will be for my favourite available dip enclosure, or otherwise contact me to discuss options made to-order. Examples can be found in past social media posts. Lower-price versions are available in a plain silver hammertone powder coat by Dulux Australia.
