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
Our mini version of Run Off Groove's Tube Reamer circuit - a stripped back, bufferless Tube Screamer which also dispenses with the tone control.
This is a great, basic overdrive to add plenty of grit to your tone in true Tube Screamer style.
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: Run Off Groove Tube Reamer
Difficulty: Hard
PCB size: 30 x 55mm
Knobs required: 2
Enclosure: 1590A
Direct-Connect compatible (4-way)
