1590B
From the vendor
Simple one-knob boosts. What's not to love? Always room for one more. This one is as simple as they come, but adds a lovely oomph. Tuned to up the mids and cut some bottom, it's great for tightening things up while adding enough push to tickle whatever follows it in the chain. Kit is available with a standard sized 1590B enclosure with or without battery, or a mini 1590A (36 x 90mm) enclosure with DC power only, though be aware that you'll be wiring in a very confined space. 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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Builds are only available with full kits including enclosure. Please choose appropriate knobs.
