http://www.jimdunlop.com Please excuse the fact that I only had a cheesey little PA to demo this unit with. Once I'd finished, I realized that it will sound WAY better once used with a real PA. The tone, in the room, was great! Really loved it. It takes some practice to get used to making the word shapes with your mouth, and I think in a matter of hours, you could master it and make yer guitar talk in any language! ROCK OUT!
