hi! I've bought 77' fender jazz bass (ash +maple). I've noticed that a neck is a lil bit bowed. E string is 3mm from the edge of fretboard at 7th fret and the G string is 5-6mm from the edge. but at first and last fret g string is closer to the edge than at 7th fret. and e string is closer at 7th fret. I've measured that there is 3mm bow (difference between ends of fretboard and the middle. I've heard that is typical problem with old fender basses. Can this causeany probems? or get worse?
