From the vendor

Ed Guidry's high-gain distortion designed to recreate Eddie Van Halen's famous Brown Sound. Despite the name this thing is actually much more versatile, offering rich high-gain tone that is perfect for hard-rock styles. Doubly versatile now the board includes the optional Contour control. Multimeter required to set the biasing voltage, though its easy enough to tweak it by ear. 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: BSIAB2 Difficulty: Medium PCB size: 50 x 37mm Knobs required: 3-4 Enclosure: 1590B Direct-Connect compatible (4-way) Download the INSTRUCTION PDF
