Impetus Drive/Fuzz

Interesting circuit that covers a lot of bases without being a jack-of-all.

With the gain switch in 'spark' mode and the Gain pot down you have a drive that goes from sparkling boost to feisty overdrive. Flip it into 'flame' mode and you have a hearty fuzz that doesn't turn to mush.

Two EQ knobs for Bass/Mids and Treble give you full control over the frequency fun going on.

Available with through-hole or SMT FET if you want to save a quid and have good eyesight and steady hands.

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 will not take a battery. Knobs are not included.

Builds are only available with full kits including enclosures and vertical-mount pots. Please choose appropriate knobs.
