Chimera PreAmp

From the vendor

Sweet little box that emulates the superb tonal range of the pre-amp in the Chimera 30. We don't have that particular amp lying around to compare this circuit with, but it sounds very good indeed.

Good range, from low gain boost to high gain crunch, and a nice EQ section to move effortlessly from twangy spank to thick bottom boom.

The original uses a B2M pot, but we've added pads so you can use a dual B1M pot which is readily available instead.

Available with through hole or SMT FETs, depending on how confident you are with those tiny fiddly little surface mount parts. Pre-built pedals are only available with through-hole FETs.

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. This does not include the enclosure unless you select one of the options with it.

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.
