Hey, I want in on this!
I bought a G7th Performance 2 about 2 years ago. Loved it - easy to move around, put in place, never an issue with it, keeps my 310ce in tune. Recently it was getting harder to place without a buzz issue. I contacted G7th and they guessed it was a 'clutch' problem. Sent me a new one, and now I'm back to easy capo-ing! Great customer service!
