Alright, here's the deal. I've had this BC Rich NJ Beast for about a year, now, and I've had no problems. It's got a locking tremolo system from Floyd Rose, and though it was a bit to get used to, I did. So, on to my problem. Everytime I play something on the first or second fret on my low E and A strings, it sounds very rattley, muted, and, well, dead. This just started yesterday, and it keeps getting worse. Do I simply need new strings, or is it something with the locking system, or..? I've not been playing that long [since I got the guitar, really], and I don't know much about the technical side of it. Any advice offered would be much obliged, thanks!
