From the vendor
Deliciously versatile take on a Fuzz Face.
With NPN germaniums in the engine room this box will give you smooth, creamy fuzz tones with a standard negative-ground supply.
There's a transformer at the front end to emulate a pick-up, which makes the circuit play nicely anywhere in your chain, not just first in line.
A couple of handy pots join your standard Vol and Fuzz controls - Smooth, which lets you tame the input level, and Bias, which will change the flavour of the fuzz on tap.
We currently have stock of several different NPN cans - AC127, AC176, 2N3102, 2N3108. We'll supply a suitable pairing.
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 (depending on selected options), 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 only available with full kits, and will not take a battery. Knobs are not included.
Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
Inspired by: Tacit Blue
Difficulty: Medium
PCB size: 50 x 33mm
