Yeah so yesteray I had it replaced because it just came loose a couple days ago. No when I ever I play it sounds like... I cant explain it, its like somethings hitting it because it sounds akward. Its like buzzing. Any idea how to fix this?

I know that sound...
Hm, is it connected across the nut properly?
Is it going across anything else on its path to the headstock?
Sometimes however it just does that, and in time it just goes away, but I'm not sure why really, it just seems to do that, and then stop.

Did you string it any differrently?

that's happened to me sometimes, and I found that the nut was shaped wrong for that particular string. Examine the nut more closely, and u may see then it's too deep/shallow for your string.
