1590B · 3 knobs
From the vendor
Boutique box based on the Roland Bee Baa Fuzz.
All the same ultra-splattery goodness of the original with four different input caps on a rotary switch, so you can be the master of the bass frequencies being sent forth.
It has a spot on Matt Pike's pedalboard, so if you're into that kind of thing, what's not to love?
Includes a daughterboard for the rotary switch to make assembly a doddle.
And all this in a vertical 1590B you say? Damn straight.
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.
