From the vendor

This is part of our FuzzPup range of circuits designed for 1590A builds. 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.

A different PCB is available for 'standard' 1590B builds - see the related products listed below.

NOTE: Images other than the main circuit are to illustrate general FuzzPup V2 build style

Really skanky vintage fuzz tones. Fizzy, splattery, over-the-top and gloriously nasty.

The original circuit has a less than earthshattering output level, so this version has an added post-boost to make everything go up to eleven. Build it as a Big Muff gain recovery for more than enough output, or LPB for ridiculous levels. You can, of course, build it stock if you prefer.

Optional third pot for the Scoop modification - a worthwhile addition, honestly.

Comes with a separate daughterboard to easily mount the pots to the main PCB.

Pots have round shafts so you'll need set-screw fitting knobs. Pot spacing is 18mm.

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 daughterboard, jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.

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

Supplied with 9mm pots (round shaft)

Inspired by: Shin Ei FY2 Fuzz
