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. Everyone should have a Rat in one form or another. That's just fact. So why not get one on your board without eating up real estate? Supplied with OP07 IC, because you'd honestly be pushed to hear any difference between that and the 'mojo' LM308. Take your pick from the clipping options - Rat (1N4148), Turbo Rat (red LEDs), both of which are supplied as standard, or You Dirty Rat (germanium) which are optional. 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: Rat, Turbo Rat, You Dirty Rat Difficulty: Hard PCB size: 30 x 55mm Knobs required: 3 Enclosure: 1590A Direct-Connect compatible (4-way) Download the INSTRUCTION PDF You'll also need V2 of the general FuzzPup doc
