are you wrapping your strings in a downward angle, or going upwards? I had a friend with the same problem, because his strings were wrapped almost straight across, instead of being angled down around the post.
well i got it down to just from the 12th fret forward the a and d buzz. i did this by adjusting the bridge as much as i can and by doing about a half turn left on the truss rod
I feel so good now. I loosened up the truss rod a while ago and now the buzz after the 12th is mostly all gone. so i touched it a little more and im thinking itll be perfect tomorrow. thanks so much guys i did not wanna take this thing to a tech
