From the vendor

'Yet another Tube Screamer' came the cry. Maybe, but this could be the only one you need. This box of mid-range boosting joy is an 808 at heart, embellished with a few glittery trinkets to wow the casual onlooker. As well as the standard Gain, Tone and Vol controls we have a few switches to flip. Normal/Bright should be self explanatory. Bandwidth will give you a choice between bright with lots of mids or a full range with lots of bottom. Voice is your clipping headquarters, with standard silicon, none or MOSFET. If you want more options on a TS then you need help. 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. Inspired by: Dunes Difficulty: Medium PCB size: 50 x 47mm Knobs required: 3 Enclosure: 1590B Direct Connect compatible (4 way) Download the INSTRUCTION PDF
