I'm going to be taking my bass in for a setup in about two weeks. The guy who'll work on it is very skilled, but he does work strictly on instruments for classical playing, rahter than the jazz setup I want. I want to have him adjust the bridge, soundpost, fingerboard, or whatever to increase the growl of the sound. As this is not a request he's likely heard before, he may need some guidance as how to proceed. So how can these different parts be modified (particularly the fingerboard) to maximize growliness-- without buzzing, of course? Thanks.
