I want to adjust my truss rod, because the strings are too far away from the fingerboard... But the "hole" for adjusting truss rod is located at the end of the neck!! I can see the hole but cannot turn it with a normal hex-screw. The only way I think of is to take the neck off, adjust the truss rod, then put the neck on again. My bass is a Fender American Deluxe Precision Bass V. Any suggestion??
