Ursa Fuzz

A boutique (urgh - that word!) take on the Jordan Bosstone Fuzz.

Tweaked to be a bit thicker sounding than the original. The addition of a Voltage Sag control gives you a huge range of fuzzy textures on tap.

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.

Builds are only available with full kits including enclosures. Please choose appropriate knobs.

Simple silicon fuzz that actually cleans up really well
"I tried a similar build (WTF) and was a bit underwhelmed. I gave this circuit a try... what a dream :) 1) goes from light distortion to thick fuzz 2) sag works perfectly and 3) it's a silicon fuzz that you can actually clean up with the volume pot of your guitar. Not exagerating, this is one really nice fuzz! Build was extremely simple, just a few parts!
