From the vendor

Buffers. We all know what they do (if you don't, just look it up), and if you're running a long chain they're essential to avoid muddying your tone. Even if you only run one or two, chances are you'll notice the difference if you add a buffer. Sparke and chime abounds in the happy land of buffered signals.

This useful fella does just that, and offers three different signal tweaks with those switches, offering emphasis of harmonics, brightness or EQ. Mix and match to find your ideal setting for your setup.

Doesn't include the FX loop of the original. What do you want in a 1590B? Don't sweat it.

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 enclosures. Please choose appropriate knobs.
