Every set of strings I put on, DR, ROTO's, Dean Markley's, Daddario's ect... any brand. The E string ALWAYS goes dead within 2 days or so. All the other strings are fine, and stay bright, but the E is always goes dead. Ive also had this problem with 2-3 basses. So I'm figuring its either me, and putting them on wrong (but the A, D, and G) are fine??? Or, my theory on it is that the E string (NON TAPERED/NON EXPOSED CORE) is such a thick string, that when it angles over the saddle, its too much of a break angle, and it damages the internal windings or something. Has anyone else had this problem with their E strings going dead within a couple days? I'm wondering if a Taper Wound E string would take care of this Syndrom.
