Two Dozen - Silvertones

Drive pedal to get you tones similar to a classic Silvertone 1484 Twin Twelve amp.

This kit is based on the Eighty Seven Percent - De Stijl schematic, and doesn't claim to be a trace of any production pedal. We've added an optional charge pump to run it at 18V from a 9V supply, but if you have an 18V supply you can leave that out.

We've done some tweaking at FDHQ, and now offer two different sets of components. Ours is a bit quieter, and has a much better response from the tone stack.

Baxandall-like tone stack for a huge range of sounds.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

We've designed the PCB to take through-hole or SMD FETs, as through-hole are getting more scarce. SMD parts aren't exactly simple to work with, so you need to be confident in your abilities before tackling them.

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 enclosures and vertical-mount pots. Please choose appropriate knobs.
