From the vendor
Of course the world always needs another Tube Screamer based drive, right? Actually yes - it's a great starting platform and ripe for modding.
This fella is a TS tone tweaker's delight. More gain on tap but just as clean as a TS with it wound back. Shape that grunt with four separate frequency controls - Tone, Mids, Character and Brightness. Almost endless combinations available to match up with any amp.
All in all this is a beautiful box of blues lead tone, and it all fits nicely into a 1590B despite all the controls.
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 batteryKnobs are not included. Pot spacing is tight at 17.5mm so take that into account when selecting suitable knobs.
Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
