The more I dive into it, tonewood denialism is a concerted effort by the industry to reduce costs by selling the shittiest materials to the users (shmucks), who now will gladly eat anything up as long as it has stainless frets and "specs"
ie "you will eat the bugs and sleep in the pods in your designated 15 minute city and you will enjoy it"
There's a difference between recognizing that there are "grades" of wood and certain physical properties of materials that matter in an electric guitar vs. suggesting "tonewoods" are able to be categorized by wood type alone.
For instance, there are higher and lower grades of mahogany, but also significant variances in density, stiffness, moisture level, etc. within those grades. Thus, to make blanket statements that "mahogany" sounds a certain way or that certain pickups sound best in "mahogany" compared to other woods is just spreading falsities.
So, until the concept of "tonewood" becomes associated with something OTHER than the bold over-generalization of the tonal characteristics of specific wood species, the better informed among us are obliged to point out the misinformation when it presents itself.
To be fair, you're not wrong about manufacturers racing to the bottom when it comes to wood quality, but that's just how Capitalism works. Keep in mind, we're also at a point where deforestation is widespread and global reserves of historically popular species like mahogany and rosewood have become heavily strained.
Personally, I think it's great to look beyond the "standard" options of Alder, Swamp Ash, Maple, and Mahogany...
