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.
All this joy comes with board-mounted pots and rotary switch for the absolute minimum of off-board wiring.
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.
1590BB Enclosure (pre-drilled) is only available 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.
DC socket can be in one of three positions as shown left
If you go for the vertical-mount pots remember they have round shafts, so you'll need knobs with set-screw fixing. The rotary switch also needs a set-screw fixing knob.
