I had my new electric guitar set up at a shop because it was a mess when I got it: action too high, minor fret buzzes and such. After it was returned, it was okay but I heard a rattling near the headstock (I suspect the truss rod was broken!)
But that aside, I didn't take it back and played with it intensively anyway and around 2 months later, the high E string buzzes when played in open, 1st, until 5th frets. It is very audible on clean or distorted but when distorted it sounds so horrible!
Note: There are also fret buzzes on most strings but it only buzzes when playing an open string in the high E.
What could be wrong and how do I fix this?
