From the vendor

An updated version for 1590BB enclosures is now available. Check the related products shown below. Prepare for the total and utter destruction of your tone. Take a look into the fiery depths of sonic hell. A two-fronted assault on your sound, with a full-on filthy fuzz on one side into a pushed-to-oblivion overdrive on the over. Fuzz gain goes from high to just plain ridiculous, and has an optional destruction control which can be variable with a pot or all-or-nothing toggle switch. Overdrive is loud. Like, really loud. The transistors are cranking out so much gain it sounds like your speaker is ripped to shreds. Nasty. Both circuits are independently switched, and the order when both are engaged is Fuzz into OD. This one is not for the faint hearted. Think NIN, MBV. Total WALL OF FUZZ in a small 1590B package. Footswitches are board-mounted for minimal wiring and easy enclosure mounting. We now supply the kit with 9mm round-shafted pots so it's not quite so tight in the box. If you want the PCB without parts there's a link for that at the bottom of the page. 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 available as an option with full kits, and will not take a battery. Knobs are not included.
