Gainer

A surprisingly effective circuit considering the low parts count.

Designed to occupy the same kind of signal realm as a Klon Centaur - colourless boost/grit - it does a grand job. It has plenty of oomph on tap, but will push your signal without adding too much hair if that's what you're after.

The tone pot perfectly tweaks things to pair up with your guitar/amp combination.

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 with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.

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