Hey, My friend recently switched to heavier gauge strings on his bass but they do not seem to rest in the nut properly. Instead of sitting comfortably they get pinched by the nut, and when tension is applied to them they pop into the slots, almost as if the strings are a little too thick. To get the strings out of the nut requires popping them out. This doesn`t seem to be a problem for his lower strings, but it seems to be preventing his G from getting tuned properly. The highest i could tune it to is D# before the tuning key requires inhuman strength to turn. This leads me to believe that the nut is preventing the string from fully stretching out, as if its locking the string in place. Thoughts on this would be greatly appreciated. Thanks.
