The newer Series and MK (and most likely the other models) have an adjustable brass nut which was not a feature included in the early Series basses. I have a 1977 Series 1 with a little back-buzz, although the neck seems so straight that I have trouble believing that a truss rod adjustment is necessary. Would an adjustable nut be advisable? If so, where can it be obtained and how is it properly installed?
Please let me know.
Thank you.
