From the vendor

This here is the result of someone having the great idea of sticking a Green Ringer octave-up circuit after a Llamatron fuzz. To be honest we weren't sure how this one would pan out, but it's a lot of fun. Not exactly an 'always-on' box, but great for adding an extra element to leads and skanky riffing, or just plain experimentation. Great range of tones from mild overdrive to full-on fat fuzz, all with that upper octave. The original uses germanium diodes, but you can stick with silicon if you want to save a 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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Builds are only available with full kits including enclosures. Please choose appropriate knobs.
