I've been playing bass a very, very long time. I've either bought or received as a field tester, many dozens of sets of strings for a few dozen different basses. I recently bought a set of DR Coated Neon strings with left over funds on an Amazon gift card. I didn't really need any strings, I just wanted the orange to go on a black Gibson T- Bird for appearance purposes. I needed strings on a P-bass for a short notice gig, so I put them on, & then the gig fell through, so they've been on the Pbass for maybe a month with about 1/2 hour playing time getting the setup dialed-in and just jamming a bit to get used to the feel. They sounded great and felt a little "grippy" on my fingertips, but overall, OK. These are by no means the first coated strings I've played, but they are the first DR's. I get the bass out of the case yesterday, and the "D" string has gone totally dead. It actually sounds like a flatwound. The E, A, & G still sound great with a bright piano-string-like tone, but the D is absolutely dead. It feels and sounds like I have foam stuffed under the string at the bridge. I de-tuned the string to make sure I didn't get it twisted during installation. All seemed ok, no apparent twist, or other anomaly caused by installation. It's just totally DEAD. Anyone have experience with DR Coated Neons (all or any strings) going dead after installation?
