EDIT: I didn't have the strings in front of me when I initially posted this...they are TAPERED, not exposed core. I have a set of DRs that I threw on my Stingray5 and I couldn't get the D string to intonate for anything. Assuming I got a bunk string, I requested another set and ended up with the same results; a D string with strange overtones, poor intonation, etc. Am I missing something? Is there some trick to intonating tapered strings? I have no issues when using other strings on the same bass.
