From the vendor
We already have our own take on the delightfully fuzzy Regulus VIII fuzz, created for Os Mutantes and a key component in their signature sound. There's never enough fuzz though, so we present to you this boutique take on the circuit. Joining the self-explanatory Fuzz and Volume knobs you have a Saturation control to fatten up your frequencies, and a Clamp control which tweaks how much clipping you have going on. We've added an internal trimmer to bias Q2 as we've found it can make a big difference to the circuit. Tweak to your taste. 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.
