Gloomy Drive

A modern take on the fantastic Univox Uni-Drive.

Despite the name this circuit isn't all about the doom and sludge. It offers more traditional rock grunt and pairs really well with a slightly overdriven amp.

The "Bottom" control will gradually introduce more bass to the signal, taking you from a treble boost to full, thick and booming.

No unobtainium old stock transistors in this one though - instead we have a nice combo of 2N5088 and MPSA18, which give a near-as-dammit tone to the original Matsushita 2sc859. If you want to source your own cans the PCB has extra pads to accommodate the different pinout.

Board-mounted pots make this a quick, simple build.

Please choose your knobs to suit the pot shaft you select in the options. The vertical-mount pots have round shafts, so require knobs that fit with a grub/set screw.

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 only available with full kits, and will take a battery. Knobs are not included.

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