FuzzPup MFZ-1

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

Ooooh that's meaty. This op-amp based 70s beast throws out much more mighty fuzz than the small parts count would have you believe.

Supposedly favoured by Dan Auerbach on early Black Keys' recordings, but we're making no claims. It does sound... remarkably... like... maybe....

This little guy is now a firm favourite around FDQH.

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)
