From the vendor

NEW - we've added the option to have it without a footswitch.

Fool your vintage, fussy pedals into thinking they're the first in line.

Based on some Jack Orman magic from muzique.com, this kit has multiple configrations depending on your needs.

It consists of:

• FET Buffer

• Transformer to emulate a pickup

• Toggle switch to flip the inductance from single coil to humbucker

• Guitar tone control

• Guitar volume control

Add as many or as few of the above to suit your purpose. Squeeze it into an existing pedal or make it stand-alone. Toggle switch is a separate option, so don't forget to add that if you want to switch inductance.

Unfortunately the buffer will cause switch pop, so consider this an always-on pedal or in a loop switcher config. You'll also get crackle when adjusting the volume if using the buffer. As Zvex famously said - "Crackle OK".

Try a spot of light reading at muzique.com on buffers and pickup sims.

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. Please choose appropriate knobs.
