From the vendor

It's been said there are more pedals based on the Tube Screamer than there are grains of sand in the Sahara desert (it hasn't). Here's another, but with enough tweaks to make it worthwhile. More gain and fatter bottom end available, and all your tone shaping needs met with the Baxandall tone stack. Quirky choice of clipping on this one, with a PNP germanium transistor giving it's own flavour to proceedings. The current version of this circuit states it has two germanium diodes doing the business, so we can only assume it's been updated recently, but this one works nicely thank you very much. Nothing stopping you modding the clipping section if you want to. Power it with 9-18V depending how much headroom you want to give it. 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 and vertical-mount pots. Please choose appropriate knobs.
