Ive got a mim p-bass with wicked fret buzz at the higher frets. even though the bend in the neck doesnt look bad at all. its not action, ive cheacked that. and it only happens on my A and D strings, mostly my A string. im guessing i need to fix that little bend in my neck first. the bend is a u. if youi laid it on the floor, face up, it whould look like a u i guess. lets say im looking strait at my bass. i put the allen wrench so thats its stareing right at me. im going to turn it to the RIGHT, so that the neck's truss rod will be turning to the LEFT, loosening the rod....right? oh ya, and if you know anything that might cause one string to buzz like mad that would help to. thanks.
