Box of Bax Boost

There are many tone circuits out there, but few are as sweet and tweakable as the Baxandall stack.

This beauty manages to squeeze a Mids control in between the standard Bass and Treble, giving you an incredible range of tones on tap. Each frequency range can be boost or cut by up to 20dB, and all three are pretty interactive. The Level control can give you lots of extra boost too, so it's not just a tone shaper.

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 enclosures. Please choose appropriate knobs.
