From the vendor

The Electra - such a tiny collection of parts that's spawned countless great pedals (and no doubt some awful implementations).

What we have here is Josh (JHS) Scott's 'Ultimate Electra', as put together here.

Now, you may love the simplicity of the one-knob pedal, but don't walk on by. This is one versatile drive with the additions. The body control is pretty obvious - keep it thin or fatten up your input frequencies. Volume - yeah. Grit - keep it cleanish or crank that dirt.

Now for an added extra. Josh's design has a trimmer to set the bias of the transistor. We think it's a lot more tweakable if we add a pot in there in series with the trimmer so you can set it within a useable range above and below a set voltage. Honestly, you won't regret 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.
