From the vendor

What do you do if you want the sweet, sweet magic of a Klon Centaur in your chain, but you don't want a Klon Centaur in your chain? Here's your answer. Touted as a Klon-killer, this circuit certainly doesn't disappoint, though whether you prefer it over the mighty one is down to personal taste. Just as dynamic, every bit as versatile and with just as much magic on tap. From light, clean boost to medium drive - this is a perfect partnership with any tube amp. The original is a three-knob affair, utilising a dual-gang pot to control the levels of clean boost and drive. We've added the option of going for a four-knobber with separate controls for those. More tweaking than is necessary? You decide. 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: OD-820 Difficulty: Medium PCB size: 50 x 50mm Knobs required: 3/4 Enclosure: 1590B Download the INSTRUCTION PDF
