Have a look at this. "A dramatic and shocking demonstration of how your brain gets fooled to see something that is not there because of your biases, prejudices and expectations"

This really freaked me out, because I really could hear the words in what had previously seemed like a load of mush.
I don't think it's too much of a leap to imagine a situation where someone sees a maple board and his perception of the sound is coloured by the received wisdom on maple boards, rather than it's happening to be a snappy-sounding bass.
I've even seen Sad owners say how surprised they were when their RV5 turned out to be brighter than their MV5 - instruments DO sound different from each other of course, but I don't think you can automatically say what one will sound like by looking at the woods it's made from, especially not just the fretboard
And Alrod - you think I'm sarcastic because I say people really believe they can hear something that others can't? Surely that's better than what you accused me of saying - that they're liars? You also say "why do you bother posting on threads about tone if you can't even hear the difference?...What value are you adding?" I thought it was a debate, so I thought the fact that several people hear no difference is pertinent to that debate. I've never said all instruments sound the same, only that I think the warmoth-type list of ingredients for a tone recipe is simplistic to say the least, and, by the way, the guy who's opinions you are so disparaging about is a master luthier who has personal experience of building instruments from different woods going back 30 years - once again, because he doesn't agree with your beliefs, you resort to ad hominem arguments - "sounds like an assembly line worker to me", and the implication that he must be deaf.
Anyone who disagrees with you gets some sort of abuse.
If you do a count up, it looks like most say that if the fretboard wood does make a difference, it's insignificant compared with differences caused by other factors. So it comes down to "I can hear it, you can't, so there must be something wrong with your hearing" again.
One big circle.
Again.
