I've recently had the chance to play around with a Catalinbread V8 fuzz tone generater. It's part of their mini-pedal line which run on external power only and take up very little room on a board. Tasty little tone-cakes, I call 'em. Here's a quick vid showing the V8 played into a clean Princeton reverb with my Grosh set neck: http://video.google.com/videoplay?docid=1334393264126093750&hl=en With the gain under noon the V8 is a nice thick fuzz with a cool slight honk to higher notes. Once you get past noon the V8 goes into Tone Engine - Destructo Fuzz mode. You get some serious self oscillation to the point where, as your notes die out, your guitar's volume knob starts acting like the frequency carrier on a twisted ring-mod / Therimen. With some care you can play the pedal notes against your guitar's notes. Wild man WILD!
