From the vendor

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 version of the kit has board-mounted pots for minimal wiring and easy enclosure mounting. If you want to do your own control layout or install in a guitar you should take a look at the wired pot version. By popular demand this kit is now available in a vertical box format, while still having board mounted pots. Sweet! Now includes optional FAT switch, for three-way frequency control. Stab pot position of Slightly Offset or Inline recommended if you're adding the switch. Pot spacing is 17.5mm, so please take that into account when choosing knobs. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. If you want the PCB without parts there's a link for that at the bottom of the page. Partial kit: PCB, all board-mounted components, pots. Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED. Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included. Builds are only available with full kits including enclosures. Please choose appropriate knobs. Inspired by: Fuzz Factory Difficulty: Medium PCB size: 40 x 50mm Knobs required: 5 Enclosure: 1590B Direct Connect compatible (4-way) If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability. Download INSTRUCTION PDF
