Just picked up my bass after having a new neck put on and some strings put on at the same time. They're GHS Precision Flats, which I've been using for a while and not had a problem with, but on the E string, basically from where it comes over the saddle to almost as far as the pickup (it's a P bass) the windings are loose around the string and I can roll them back and forth with my fingers. When I play there's a bit of movement as my finger foes over the string. Does that make sense? Anybody had this problem before?
