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

Based on a COT50 boost/OD box, but with some handy mods by Fred Briggs over at Revolution Deux.

As well as the single bias control of the original, there is an additional Nature control to go from full boost to Range Master-ish world. Slightly softer clipping than the original, and caps altered to make it all a little thicker round the edges.

We've added a Master Volume.

The circuit will take you from clean boost to light overdrive, and can crank enough juice out to really push an amp into new territory. Highly pick-responsive. A great addition to any set up.

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: Clock of Tone / COT50

Difficulty: Hard

PCB size: 30 x 55mm

Knobs required: 3

Enclosure: 1590A

Direct-Connect compatible (4-way)
