FA-1 FET Preamp

Great clean boost with active tone circuitry.

The Edge uses one, if that means anything to you.

Does exactly what it says on the box, and does it very well. Low impedance, 26db boost, and a toggle switch for flat/low cut response.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

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 can take a battery if desired. Knobs are not included.
