1590B
From the vendor
The raucous cousin of the Ramesses Fuzz, this Big Muff-based beast pulls no punches. The scoop pot gives you a huge range of tonal possibilities, making this a simple but versatile muff to mess with. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. Built on the Ramesses PCB. 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: LSTR Difficulty: Medium PCB size: 50 x 50mm Knobs required: 4 Enclosure: 1590B Direct-Connect compatible (4-way) Download the INSTRUCTION PDF
