Tonewood deniers are in the same category as flat earthers.
Completely out of touch with reality.
They are in touch with their reality -- for a number of reasons, tone wood on solid body guitars and basses can become increasingly meaningless as other factors come in to play:
- Active Preamp,
- Pickup Tone and Sensitivity,
- Amp Coloration,
- Compression,
- Effects,
- Weight and Aesthetics Impacting Perception of Tone
- and Confirmation Bias.
The way you've voiced your take may be in the "confirmation bias danger zone...!"
I have experienced differences in tone and sustain based on differences in body wood, but these are subtle and subject to so many factors that the only certainty is that one cannot reliably be assured of the impact of tone wood from bass to bass. It's very much worth talking about and listening for, but it is not as simple as we'd maybe prefer it to be.
Here's part of what I think has changed in bass wood choice (I'm no expert, this is just my sense of some of what has happened.) --
In the late seventies, heavy, hard woods like Ash and high mass bridges were the fashion -- brighter sounds and longer sustains suited the recording tech and musical tastes of the seventies. So were natural finishes, suitable to the grain of Ash.
But things change. Amp tech began to change (with GK in my view) and bring out the sustain and snap of basses not made of ash and brass. So the brighter tones needed to modernize the sound coming from the Ampegs and Acoustics and Kustom Tuck and Rolls was no longer necessary in the design of the bass. Stage theatrics became fashionable in the big hair eighties too, and lighter basses started coming out of Japan and onto world stages. The move to digital recording and home listening also had an impact - the scooped SWR and Eden sounds were very suitable to the new sound of CD's... but eventually that newness wore off and everyone wanted to go back to thump and drive of an old bent plate bridge alder P Bass.
Take it to 2021, and people are migrating back to passive pickups. A decade of smartphones and streaming (and an era of global political, social, economic, and environmental challenge) drives a need to seek more natural sounds and a return to the vintage vibes of decades perceived as better and simpler.
Anyway, there is a lot going on. Our times impact our ears, and what we expect to hear and seek out in an instrument, a performance, or a recording. Tone wood does too, but it's not always so simple. YMMV
