I do not deny that differences in structure, density, torsion resistance, or the way a neck is attached to a body result in damping of some harmonics - this is what makes an instrument's timbre, after all, it is why a bass guitar is different than a flute or a wash tub bass, and this paper definitely demonstrates that this is the case, as well as makes the case for dead spots. I still say so what - I can't see in this study that rosewood was compared to maple, or how ash was compared to alder or mahogany, and what reliably, consistently measurable and *perceptible* differences those materials make to timbre in an amplified electric instrument, so it does *not* address the argument at hand. What woods make which differences, and why? It also does not address open or closed grains, which is what one respected fretboard=tonewood arguer here was asserting. I *can* hear the difference between one P bass and another, what I'm saying is I can't reliably attribute any of those differences to fretboard wood or body wood. I've owned and played many different basses since 1982: ash with rosewood and ash with maple, alder with maple and alder with Rosewood, ebonol, Pao Ferro, agathis, basswood, even a couple that were plywood (an Ampeg Big Stud with Rosewood and blocks/binding and a Harmony with maple and crappy finish that chipped off when you picked it up), a couple of both fretted and fretless Jazz basses with different boards, and seven or eight P basses with a variety of combinations. I'm not an expert, but I sure as heck didn't just fall off the turnip truck yesterday, and my anecdotal evidence can take on the anecdotal evidence of *anyone* else on this forum. I'm not interested in anecdotal evidence or subjective descriptions. You can have them and keep them, and even share them as opinions, but it's when you start swearing that it's truth that I start to have an issue with it, because according to my equally valid anecdotal evidence, it's false.
So long as people are using terms like "warm," "sweet", "bright" and "focused low frequencies" to describe their instruments' materials (subjective meaningless terms, Roger Sadowsky), attributing those differences to how much harder maple is than rosewood (which is simply not true, Mike Tobias), and being completely inconsistent about it (somehow ebony *and* maple are both brighter than Rosewood?? Is it density, hardness, or how open the grain is that determines "warmth" and "brightness"? The people arguing for tonewood do not agree on this.) this debate is going to continue, and people are going to keep asking questions and calling BS. You're entitled to your opinions, and maybe they're not even factually wrong, but if you're going to assert them, the burden of proof is on you, not the skeptics.
