From the vendor

One PCB, two fuzzy possibilities. First up is a very popular boutique box built to nail the fuzz tones used on Pink Floyd's The Wall, and nail it it does. The Pink Pig circuit has articulate highs, fuzzy lows, and less of a mid scoop than is typical for this type of fuzz. Add to that a toggle switch to alter the mids from 'flat' to 'hump' and you have a very versatile fuzz box. Next up we have The Bell, a boutique box based on the Pink Pig with a few tweaks (though the makers claim it isn't based on any particular model). Gone is the mids switch, replaced by a 'colour' pot for more control of that scoop. The two circuits are sonically very similar, with only a few small variations in component values other than those mids controls. 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.
