From the vendor
Another winner from the brains at RunOffGroove. This one is their take on nailing the tone of a Marshall Super Lead.
This really does deliver some great high gain tones with a pretty low noise floor. Eschewing the traditional three-band EQ you might expect, this box keeps it simple with switches for Bright and Bottom, to give you more sparkle or bass grunt as you wish. You;re going to tweak your tone before you hit this anyway, right?
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. The PCB is designed to take through hole or SMT FETs. SMT are cheaper but fiddly to work with, so only opt for those if you're confident you can handle them.
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.
