1590B · 3 knobs
From the vendor
Far from cheesy, this box is bursting with full-on fuzzy madness. Super high gain tones to pound your sensibilities. V2 now has a separate daughterboard for the rotary switch to make it much easier to line it up with the pots.
Incredibly versatile thanks to the famous four-way tone section rotary switch, giving:
• Tone Bypass
• Mid Scoop
• Mid Boost
• Gated (very, very silly but mucho fun)
Includes a modified output stage for extra volume, as the original was a little lacking. Many thanks to Plesur for the details of that mod in the Feta Complis build doc.
And all this in a vertical 1590B you say? Damn straight. AND it's great on bass.
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. The rotary switch may need to be cut to length.
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.
