Similarly as with musical instruments, everyone’s ear canal, skull bone structure, fleshy padding, and signal path (neurology) is individual and different, so I can accept that others hear things I don’t, even if to me it makes little sense, as I’m not an engineer or any sort, I’m a musician. My job is to use *my* ears to choose an instrument and other equipment to amplify it, and I’m empowered to use *my* money to execute those choices.
Luthiers are not scientists. I mean, they could be, but unless they’re backing up their opinions with data that’s collected using a reproducible and peer reviewed methodology, they have opinions, just like you and me. They make their choices for woods based on their opinions, which maybe suit their ear canal/skull/neurology in some way or maybe it suits their sense of how to coax a profit margin out of a market (and nothing wrong with that). They’re essentially highly specialized artisanal cabinetry makers. Their primary expertise is construction, not getting a good sound out of an instrument. That’s my job. My ears matter a lot more to me than their ears matter to me, and it’s my money, so I’ll place my bets where I like.
IME and IMO:
I’ve owned a lot of Fender P basses. I’ve owned and swapped and played pretty much every combo of ash, alder, rosewood, maple, and others available, across multiple examples and pieces, with similar pickups/strings/amps. There are slight individual differences between one and another, which must be attributable to the wood, but which 1) can’t be attributed to a species of wood, and 2) make pretty much no difference to anyone except me. Again, that difference made to me matters, it’s my job and it’s my money, but making broad generalizations about wood species seems to me to be very ridiculous. I’ve heard maple that’s warmer than rosewood, alder that’s brighter than ash. A couple of ebonol fretboards I’ve owned sounded fantastic, and that’s the same material used to make bowling balls.
Fender is now using pine where they used to use ash. Two very different woods.
So unless someone has some actual science that matters to what I’m hearing or not hearing, that’s my opinion, and Roger Sadowsky or anyone else is entirely equally entitled to their dissenting or agreeing opinion as well. A luthier’s opinion on what woods matter when to me isn’t much use to me, I’ll buy and play what I like, based on what I hear or feel in my hands. They’re not entitled to my money just because they have a big name, there are lots of big names around. The worlds of rock and roll, Jazz, R&B, etc are full of much wealthier and more successful people playing off the shelf Fenders that are more or less identical to what I’ve bought. Surely their opinions matter as much or more than a well-known luthier. However, at the end of the day, like I said, my money, my ears, my choice.
I’m mystified by people who choose to outsource their opinions and use other people’s opinions in a desert of supporting data and facts. All power to you, but whoa up on the certainty, so far all we’ve got is opinions.
