I love the tones, I really do. It's bright and punchy, with lots of growl that I can beat up on for hours. I've currently got a set on my MIM Fender fretless Jazz. As much as I love the bright tones for my fretless, I'm still excited for when they'll finally die and give me some good ol' thump. A few problems, though! My A string is buzzing. Like, really, really badly. But only when I play it open, and above the twelfth fret. In fact, they all buzz buzz really horrendously above the twelfth fret, and the low E starts buzzing about the seventh. With the A, if I play it open it buzzes really harshly, but if I put my finger down right next to the nut on the fretboard, call it A-eighth-step-sharp, and higher, it stops. These are issues I've never had with my other strings. The bass came originally with a set of unknown flats that I enjoyed immensely, but I thought I'd try these new guys. Is there anything I can do to eliminate the buzz? As near as I can tell, they're the same gauge strings as the older ones (.100-.043), but I don't have the tools to make the exact measurement. Help, please? I'll clarify any questions.
