Solar Face Fuzz

Who doesn't love a Fuzz Face? Well, weirdos maybe. Who wouldn't like to tweak their Fuzz Face bias on the fly? Again....

All the lovely fuzzy goodness of the FF but with an external bias control. Twiddle it to compensate for temperature variations which mess with your germaniums, or just to change the flavour of fuzz to your liking.

Kits available will change depending on what we have in stock. Currently they are:

• Newmarket CV7007 (OC77) (PNP Germanium)
• Russian + whatever we have in stock (PNP Germanium)
• BC108 (NPN Silicon)
• 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 cheaper silicon option gives a slightly harder fuzz - think along the lines of Dark Side of the Moon solos. - a classic sound in its own right. We've included spots for a couple of smoothing caps for the silicon version to avoid any squealing at higher gain settings.

Please make sure you select the right combination of options, i.e. don't order the NPN Silicon along with the Power Inverter parts - it opens up a world of email pain!

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.
