Mutantes Fuzz

The FuzzDog take on the delightfully fuzzy Regulus VIII fuzz, created for Os Mutantes and a key component in their signature sound.

This version includes a Body control to thicken it up a bit from the thin, raspy stock setting (which is great, but y'know... versatility and such), an optional Clipping control which changes the clipping from symetrical to asymetrical at the turn of a knob.

There's also the option of a toggle switch to take the clipping out altogether, giving you a crunchy OD if that's your thing. The opinion at FDHQ is leave well alone. This is a fuzz.

Designed for board-mounted vertical pin pots (which have round shafts), but you can wire up 'normal' pots if you prefer.

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 will take a battery. Knobs are not included.

Difficulty: Easy

PCB size: 50 x 20mm

Knobs required: 2/3

Enclosure: 1590B

Direct-Connect compatible (4-way)

My new fav fuzz 5 product stars
"Was pleasantly surprised at how good this thing is! Kept it simple as a 2 knob job- blend and volume. Plenty of gain on tap and can sound so thick through a deluxe reverb it sounds like it's going to collapse in on itself. Tons of character and very recommended." BrettS - 26/07/2017
