From the vendor

Fat, heavy fuzz from this hard to get vintage circuit. Really nice tone control gives you a lot of tweakability. The original is a simple two-knob affair, with the fuzz being set to full by a fixed resistor. We've added the option to include a fuzz pot, but to be honest this thing works best stock. All or nothing. Gung ho. 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 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.
