I have a 2003 4 string Warwick Thumb bolt-on, and the guy who previously cranked up the truss rod pretty good, and the fingerboard has small cracks all along its length. While it still sounds awesome but not flawless, I'm worried about the longevity . . . How do I go about getting a new neck/fingerboard/truss rod? And I am still amazed that it sounds as good as it does considering the extent of the cracking!
