From the vendor

Boutique box of buzz based on the Jordan Bosstone. This builds on that solid base by adding a three-way treble cut toggle switch and a really useful starve or 'WTF?' control. If you've not used a fuzz with a starve pot you're in for a treat. It works really well on this circuit. The original boutique box has a boost control on a second footswitch, but meh. That's what boost pedals are for. We've dispensed with that and kept it neat and tidy in a vertical pedal format rather than horizontakl. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. 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, 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. Builds are only available with full kits including enclosures. Please choose appropriate knobs. Inspired by: WTF? Difficulty: Easy PCB size: 50 x 32mm Knobs required: 3 Enclosure: 1590B Direct Connect compatible (4-way) Download the INSTRUCTION PDF
