I hope somebody can give me a clue on what to do. I have put a set of Elixer strings on my fretless Cort Artisan 5. All strings fit perfectly except for the B (It's a .130). The nut and bridge aren't wide enough for this string. How do I solve the problems??? For filing the nut there are 3 options. 1: Keep the existing center 2: move the center closer to the E string 3: move the center closer to the edge. (I hope you're still with me here...). What's best??? And what can I do about the bridge?? Thanks for any help you can give me.
