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.
Kit includes: PCB, all components, hook-up wire, 3PDT footswitch for true bypass, jack sockets, DC socket, battery snap, LED. Enclosure (pre-drilled) is optional and will take a battery. Does not include knobs.
PCB size: 50 x 33mm
Knobs required: 3
Direct-Connect compatible (4-way)
If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability. Pre-builds only available with vertical-mount pots.
