OK! I need some help here from all of you experts out there. I recently changed the strings on my AmStd Jazz-V. I had D'Addario Half-Rounds on it and was actually quite pleased with the sound. However, on the recommendation of none other than Roscoe Beck ( I posted on his site and he actually does answer people's posts ), I changed them out to Labella Rockin' Steels. This was to get a better "B" string. Well, now for the problems. 1. The "E" string rattles like blazes when you play it open. I checked it and it seems to be just barely touching the nut. I checked the relief in the neck and it is OK. I lowered the bridge as low as I can get it without rattling everything and it still rattles. I did not have this problem with the D'Addarios. They worked just fine. I don't play open strings very often, but there are some times when I use them. This sounds like "HELL" when I play it. Any solutions, experience, help, etc., would be most appreciated. 2. The "B" string itself sounds almost like it's in a echo chamber whenever it's played, anywhere in the neck. It's also kinda muddy. I lowered the pups to see if maybe I was getting some mag-field interference, and it has helped, but not completely. The other 4 strings are fine. I kept lowering and it reached a point where there was no further improvement, but the problem was not cured. Do I just have to wait for the string to deaden a little? Will this cure itself over time? What!!?!?!? I don't want to throw out a brand new set of strings, but I'm just about ready to do that. I don't normally use round wounds. In fact I really dislike them, but I thought, based on Mr Beck's recommendation, I would try them. He said these are his favorite strings. So, I bought a set. I guess I should've stayed with the half-rounds and flats that I normally use and like. Oh well. Any help here would sure be appreciated. Thanks!!
