Some highly sought-after vintage fuzz tone going down. If you want to get hold of an original - good luck. If you want the reissue, prepare for some ho-hum disappointment. The tone-boost on the new version has so much volume drop its borderline unuseable. So, build your own.

Great Octave-up fuzz (though not as prominent and extreme an octave as some), with a handy clean-blend control to calm things down if necessary.

This is a massive amount of fuzz in a small 1590B enclosure. Boxing it up is a little fiddly, hence the difficulty rating. We now supply the kit with 9mm pots (round shafts) so it's not quite so tight.

Footswitches are board-mounted pots for minimal wiring and easy enclosure mounting.

Formerly known as the Flender, this is in no way related to the pedal offered by RonSound - they had the name first so we agreed to change it.

Partial kit: PCB, 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.

Enclosure (pre-drilled) is only available with full kits, and will not take a battery. Knobs are not included.

Difficulty: Hard

PCB size: 90 x 45mm

Knobs required: 4

Enclosure: 1590B

"My second build in a 4 kit purchase/binge from Fd to help get me through dry + vegan January! A tight squeeze for sure but otherwise really easy & fun! I ve wanted a FB since I saw one on frusciante s pedal board on the mother s milk tour (geez I m getting old). Fantastic kit. A lot of fun coming my way; it sounds so good!" Ian - 09/01/2018
