From the vendor

What? Yet Another Fuzz Face? Indeed, but this is a real doozy. Tweaked to provide silicon Fuzz Face vibes with a lot less background noise, this really does the job. Cleans up just like the real thing, and loves to scream vintage vibes when pushed. There's a very useful tone knob which doesn't really act like a tone knob does. It adds a bit more top end and bite which is great but maybe too subtle for some (not us - we think it's perfect). You have the option to go with a more traditional full-range tone control if you prefer, but it'll work in reverse. Swings and roundabouts. It's just a jumper, so easy enough to experiment with. The original uses a 50KA volume pot, but we found 100KA feels better. Totally up to you. Make your choice at checkout. Unfortunately the PF5102 FET used in the originals is gone daddy gone, but the J113 we provide sounds identical. We know - we have both to hand. Supplied with board-mounted pots with 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 only available with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Builds are only available with full kits including enclosures. Please choose appropriate knobs.
