From the vendor
Tube Screamer on steroids would be an unfair description, but there's no denying the bedrock this box sits on.
Retaining the mid-range goodness the TS is famed for, this manages to be a lot more articulate at the top and bottom ends of the frequency range.
Front-loaded with a Boner Boost, you can increase your input signal to breaking point before it hits the main circuit, with similar results to giving a tube amp a nice big push.
A super high quality op-amp makes all this as quiet as can be. Well worth the extra couple of quid.
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.
