On the other hand, what this is not able to explain is why older guitars resonate more if the wood has nothing to do with it. Maybe because older wood helps the guitar hardware resonate? I don't know. Definitely my 15-20 yrs. guitars sound louder, except my floyded old strat - it still sound a bit dull despite it being 15 yrs old.
My guess would be pick-up deterioration towards a partly-'microphonic' state.
Microphonic response means it will begin to receive those tonal ualities that
the naked ear can also appreciate, and which are DEFINITELY influenced by
the resonance of the wood of the body and neck.
Take 'microphonics' out, and all a pickup can perceive is magnetic disturbance,
mostly from string movement --which in turn is influenced vastly-more by the
strings' contact area with, and hardness/resonance of the nut and saddles,
than by the resonance of the body/neck/etc.
Scott makes the mistake of dismissing tonewood influence ENTIRELY, but IMO
he's not mistaken to dismiss it as insignificant, at least where the pickups are
acting like a pickup is supposed to.
