Fat Pig

Big fat tube-like drive.

Cascading CMOS gain/clipping stages, much like the Red Llama, give a warm breakup across a range of gains. Bluesy grit through to almost too much saturation, with a MORE toggle to push it that little bit further. Tweak the tone with the variable low-pass filter and you've got yourself a winner.

Power with 9-18V, though honestly it sounds great with just the 9.

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

You will need a multimeter to tune this circuit. You *could* do it by ear but it's not recommended.

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.
