From the vendor

Tube Screamer tones tuned specially for you low-frequency fans.

All the fun of the little green wonder with extra controls to keep your bottom end intact. The single tone control is replaced separate bass and treble knobs, and a mix control lets you blend between clean and dirty signals.

Use it as a slightly gritty boost, or crank that gain to get things really dirty.

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.

Inspired by: TS9B Tube Screamer
