Ultra-Fk Fuzz
NOTE: This does not include the DIP switch options recently added to the original.
A behemoth of bass fuzz. If you want to take down the walls at a molecular level, this is the fuzz for you.
A bass fuzz at heart, this will work just as well with guitar, throwing out massive, saturated doomy sludge with abandon.
Take control of the madness with controls for:
- INPUT - input signal level - higher = more saturation
- MORE FK - how much more gain and volume you want when you kick in the second footswitch
- OUTPUT - master volume
- SLOPE - essentially your tone control, adjusting the frequency balance
- NOTCH - cut your mids or leave them in
- SHIFT - moves the cut-off frequency of the notch
The last three controls are very interactive. The pedal this is based on had a three-way switch for the shift control. This version can be built with a three-way toggle switch or a pot that will give you much more control.
Board-mounted pots (and switch if you're using one) make this a quick, simple build considering the amount of controls. Coupled with the seperate daughterboard for the footswitches, connected to the main circuit by a 7-way ribbon cable), this is as neat as it gets. Only six off-board wired to connect.
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.
If you want the PCBs without parts there's a link for that at the bottom of the page.
Partial kit: PCBs, all board-mounted components (not footswitches), 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 available as an option 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.
