My luthier has told me that my bass' fingerboard is getting thin and that I should consider having it replaced. There is enough rosewood currently that I needn't have this work done immediately, but in all likelihood, I will have to have it done in the not-too-distant future. A new bridge may be in order at that time, too, because of the change in fingerboard thickness. I have 2 questions--am I risking damage to my bass by postponing the replacement of the fingerboard; when I do ultimately replace it, should the new one have the same profile as the one it replaces? Thanks.
