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. Our mini version of Run Off Groove's Grace and Big Daddy circuits - two excellent buffered power amp-based drives. First up we have the Grace. Unlike some power amp-based designs that go all-out screaming distortion, this is tuned for a range from light break-up to vintage amp overdrive. The buffer gets rid of any loading of the guitar signal, adding sparkle and transparency. A great pick-responsive base for your dirty tone. The Big Daddy follows the same basic lines but the input buffer is replaced with a FET gain stage, pushing the power amp stage into much heavier distortion. Just as responsive as the Grace, but the gain goes from medium break up to.... eleven! Parts are supplied for both kits, so no need to decide right now. 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. 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: Run Off Groove Grace / Big Daddy Difficulty: Hard PCB size: 25 x 45mm Knobs required: 2 Enclosure: 1590A Direct-Connect compatible (6-way) Download the INSTRUCTION PDF Please also read this general guide to FuzzPup builds. Note: image with circuit board in the enclosure is to illustrate the way this kit connects.
