From the vendor

'ANOTHER Fuzz Face?' we hear you sigh. Indeed, but it's a doozy.

Vol and Fuzz controls as you'd expect, but joined by an (input) Bias knob to remove woof and give you essentially a pre-gain control. Add the Contour knob into the mix, controling mids, harmonics and sustain and you're onto a winner for sure.

Kits available will change depending on what we have in stock. Currently we're offering:

• A mix of Russian + other cans we have in our parts bins (PNP Germanium)

• NOS military spec CV7007 (OC77) (PNP Germanium)

• No cans please - I have some sweet action of my own.

The PNP versions can be wired positive-ground and used with an isolated power supply, or go for the optional on-board voltage inverter to daisy-chain power with your standard pedals.

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.
