Because he's been making world-class instruments for over 30 years, and is therefore likely to know all the sales tricks? He's hardly likely to say "I think this instrument should have an ebony 'board 'cause it would look nice and I just got a really good deal on a stack of blanks."

Skepticism is healthy, I think - though it can cross over to cynicism?
I would simply say that I have heard from other luthiers whom I respect and who know a great deal more than I do that neck woods do make a difference. They generally go on to say everything makes a difference, though of course relative contributions of the various bits vary.
I am now at a stage where I think most of the tone of an instrument resides in the neck as opposed to the body. A slightly unusual point of view, perhaps.
Took me a while to come to this conclusion, and it's based partly on observations of others and partly on my own (e.g. By swapping necks about, trying necks with graphite rods, trying fully graphite necks on basses I own, necks with steel rods, necks of different dimensions, necks with different boards, etc, plus a lot of modding of pickups and preamps and bridges and tuners and whatnot).
I'm not aware of any well run double blind studies in this area. They would probably help.
