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.

From a mild boost to a big, fat distortion. This is a little box of antipodean boutique magic which proves you can have your cake and eat it.

Huge range of distortion available, and a presence control to give you some mid-range whallop.

Word is the original has been made using two different ICs at different times, so you have the option of which you'd prefer. The differences are subtle, so decide for yourself by trying both!

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: Hotcake

Difficulty: Hard

PCB size: 30 x 55mm
