I've had these D'Addario XL 10-48 Chromed flatwounds on my casino for sometime now. I got to say, This works good on this guitar, for the intended purpose. These are heaven on the fingers, and once you get use to the feel, they are nice. Nothing contributes to good authentic, surf music like flatwounds. They get this sound That round wounds just can't get for my hearing aids. Yea..your gonna over-shoot the mark a few times when ya start out, being as they are slicker than snot. But I sure like them on this guitar for Rock'n Roll, or surf, smooth jazz and more. This guitar also has a different bridge, which I also like. These are nice strings. And, I think flatwounds last longer than roundwounds myself.
