I had this problem for a long time now, well to be exact in what string. E A and 5th - 13th (ithink) Fret of B string. I had ask the guitar shop i always go to and when i said the problem they say adjust the truss rod. Well, ahmm. I didn't try it yet. because i have read in some maintenance about guitar that the truss rod should be adjusted with knowledge.
Questions.
So ahmm.. is it really the truss rod ?
And if it is the truss rod and i got the equipment (the wrench i think) should i turn it clockwise or counterclockwise ?
Or i should just go to the guitar shop and let them do the job ?
