When i play the open b string, there is some buzzing caused by the first fret because the string is too close. I dont have this problem with any of the other strings (not even high e) and tyhere is no problem when any of the notes on the B are fretted, so its just a problem with the open string.

The trem is at the proper angle, the action is not too low and the neck is not warped or at a bad angle.

I think it might be a problem with nut height. Its a locking nut btw. Anyone have any similar problems like this?
Sometimes my strings buzz on my Ibanez, but thats rarely, I sort it out by just pulling the string upwards (towards my head) or downwards to sort it.
I pull it right by the trem.
