That's very interesting, Dr. Jim, I'd never seen that post before. Particularly interesting since I was talking recently to Carl Pedigo, longtime head luthier at Lakland, about this very subject. In his view, body wood plays a bigger role in tone than fretboard wood. (Keep in mind, of course, that this is my recollection from a couple months ago, whereas we have a post typed from Roger Sadowsky here.I hate to break it to you, but no less an authority than Roger Sadowsky has come on these forums and stated unequivocally that in his experience, fingerboard wood has more effect on a bass's tone that the instrument's body wood. Search is your friend.
This post of his addresses most of the tone issues/generalizations and ends with some superb practical advice:

Carl's reasoning was along these lines: Fretboard wood is divided into small chunks by frets, and is a thin layer on top of the neck itself--thus, there's not much material to affect the strings' vibrations compared to the bulk represented by the body wood. And to his ears, there's little difference,
Ultimately, I think Roger's last statement (which is good advice, I agree!) indicates that in the grand scheme of things, fretboard wood doesn't matter all that much. So the opinions of these esteemed gentlemen probably aren't really far apart.
