I've been playing bass for almost a year now, and I recently bought a new bass because I though it was better than my old one. But anyway when I put on my E I let it set and stretch. Then when I begin to tune it UP or DOWN to E or D it snaps. This has happened 4 different times. I dont think it is the strings they all have been Slinky Erine Ball. Last night I was able to put a thick A string, .085, on there I can tune it up and down to E and D. I asked a friend of mine and a couple of other bass players and they have all said they dont know what the problem could be. It breaks at the tuner. I dont turn the tuner fast, I turn it very slow. I trim them all right, measure it so the string goes around the Tuner 3 times. Anyone ever had this happen or know what is wrong with it?
