Still have the stock strings on my cheapy Ibanez bass I just picked up a few weeks ago. All of a sudden the E string suddenly hisses or kind of rattles(?) like it's full of sand or beads when played. It's really weird and I'm a complete noob so please forgive me for not understanding what's going on. The sound is in the string itself though it does kind of come out of the amp a little. None of the others do it. I just noticed it a day or two ago. Don't know how else to explain it, when played the E sounds like it has sand or small beads hissing around in it. What gives please?
