Pep Box

Silicon version of the WEM Pep Box, which replaced the earlier germanium version in 1966.

Lovely full-on trebly fuzz tones.

We've included the option of an external bias control as tweaking this can give you some great gated, dying battery type sounds. If you'd rather stick with a two knob unit the bias is an internal set-and-forget trimmer.

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 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.
