From the vendor

This is part of our FuzzPup range of circuits designed for 1590A builds. Please read the general build doc available here and ensure you're happy with what's involved. They're not especially difficult, but working in a confined space can be fiddly. Take heed.

Of course there's nothing stopping you using these PCBs for 'standard' builds. They're Direct Connect compatible.

Take Craig Anderton's Tube-Sound Fuzz circuit, add some tiny tweaks, give it a silly name.

Well, it seemed to work, and the circuit is a doozy, so good luck to the fella.

Great range of tones from mild overdrive to full-on fat fuzz, with warmth all the way.

Circuits with such a low parts count shouldn't be capable of such versatility!

Also available with a standard format PCB for 1590B builds - check the related products listed below.

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.

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