Fat BOO!

Class A boost that gives you oodles of clean headroom, with some tweedy grit on tap at the top of the drive control.

Wind in the bass, or pull it back some before your signal hits the gain stages - match it perfectly to your pickups. The treble is a passive bleed at the end of the circuit to tame the highs if necessary.

Available with either through-hole (more expensive) or SMT (more fiddly) FETs.

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.
