From the vendor
Transparent drives... lots of them around, but there's always room for one more. This one is a beauty. It sounds sweet into a clean amp, giving a large range of break-up options from low to medium-high. Into an already overdriven amp it'll push it right into the creamy sweet spot. Standard Vol, Drive and Tone controls aren't enough for this puppy. Two three-way switches give you high-cut and clipping options to make this one very versatile box that'll tweak to match any set up. 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 enclosure and vertical-mount pots. Please choose appropriate knobs. Inspired by: Golden Pearl Difficulty: Medium PCB size: 50 x 33mm Knobs required: 3 Enclosure: 1590B Direct-Connect compatible (4-way) Download INSTRUCTION PDF
