Bad Mofo Bass Drive Mini

From the vendor

Mini version of our Bad Mofo drive. If you like a bigger box, go check that out.

Some special lovin' for all you low-end dirt junkies. The Bad Mofo bass overdrive preamp.

DRIVE and LEVEL pots give you control over the amount of dirt and volume. TREBLE is a low pass filter to cut your top end for just the right amount of fizz. Nothing groundbreaking there, but wait....

We have a four-way rotary switch to give you four completely different sounds. Silicon, Germanium and LED clipping are available, as well as clipping bypass for extra crunch and minimal clipping.

Top off those goodies with a very effective buffered BLEND control to dial in as much dry signal as you like.

The only bass dirtbox you need? Maybe. Be sure to take the path of the righteous.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

No longer particularly fiddly - we've updated the kit with a separate daughterboard to mount the rotary switch. When using header pins it sits exactly in line with the pots. Happy days. No longer supplied with the JRC4562 op-amp as they're simply not available. 4559 supplied instead, and sounds identical.

If you want the PCB without parts there's a link for that at the bottom of the page.

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.
