Filth Fack! - Crazy Germanium Fuzz
Now available with silicon transistors in place of the usual germanium for a different flavour of fuzz and more temperature stability.
Take a Fuzz Face, mess around on the bench, add some pots and a sprinkling of crazy dust and you have this beast.
Classic, noisy five-knobbed fuzz box with stability, compression, gate, drive and volume controls. The fuzz comes from a pair of specially selected germanium cans which can produce tame, soothing fuzz tones or veer off into wild oscillations and gated madness with the twist of a knob or two.
Most builds have fiddly off-board pot wiring. This board has connection points for all lugs of all pots. The fiddly work is all done in the copper traces. Sanity maintained.
This version of the kit has WIRED pots - useful if you want to do your own control layout or install in a guitar. A board-mounted pot version is also available for a quicker, neater build.
The enclosure option for this version will take a battery, pot spacing of 20mm - please take that into account when choosing knobs.
