Vox MkIII Treble and Bass

From the vendor

Earning it's rightful place in the history of the Tone Bender, this little chap is pretty hard to come by.

Silicon-based Tone Bender topology, but with a Treble/Bass knob instead of your usual Fuzz control - this fella is full tilt full time.

The original uses 2N2926 cans, which are now obsolete and very expensive if you can find them. We've done a lot of experimentation at FDHQ, comparing modern transistors to the originals (Many thanks to Markus at Reeves Electro for supplying the mojo). It's pretty hard to make this thing sound bad, but we've finally made our choice for what will be supplied with the kit. If you're going PCB-only, don't sweat it too much. Your usual suspect low-gain BJTs will all work. Swap-out and see.

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.
