All-time classic fuzz. Huge, smooth sounds available from this great circuit. Super-saturated lead tones, or great chord work with the guitar volume knocked back.
The choice of transistors will grow as more experimentation and fiddling goes on at FDHQ. There’s plenty of room on the board to take the meatiest of vintage cans. Right now we’re only supplying AC128/AC125 or a combination of Russian MП16Б, MП41A and AC125/8, or you can have the kit without cans if you want to source your own.
You can even swap a couple of components and make yourself a Marshall Supa Fuzz (much fatter, bassier tone than stock) or a Vox Tone Bender MkII (slightly bassier, not a lot).
The circuit has board-mounted pots for minimal wiring and simple enclosure mounting.
Would qualify as easy but you need to adjust two trim pots to bias the transistors. A multimeter is recommended, though you can do it by ear.
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.

Use in conjunction with a Power Pump or the charge-pumped daughterboardif you want to power the PNP version on your standard polarity daisy chain.
