"This excitation makes it through the body to the strings, and whatever they do in response, must be captured in the sound."
Well not really Rob, just because something seems intuitively true doesn't make it so. Making cables out of Silver MUST make them better than Copper? I think we all know the answer to that!
For one thing, how are the body vibrations fed back into the strings? Surely not at the bridge since that is a "node" a point of zero velocity like a sound hitting a brick wall.
I think the "feedback" situation is a red herring and a different mechanism (if there is one!) The speaker directly excites the strings which excites the pickups which goes back into the amp....Yes, an acoustic guitar will feedback earlier and at a lower level than a Tele but then an acoustic is a "resonant system" and is louder than the solid guitar to start with. All else being equal, a mic with high sensitivity will feedback earlier than one of lower sensitivity.
My son has a Tele clone and a Ricky 330 (a proper one!) They are he tells me both about the same for feedback onset. The 330 is of course a 'semi-sold' design and WOULD be more susceptible except that it has weedier pickups than the Tele.
I can't find that YT about the 'air guitar' but he sent me the link so I shall ask him for it.
Another related factoid? I needed a simulated pickup (sans strings) to terminate amps for tests. I put a single coil in a diecast box and filled it with wax. Given enough gain* that bugger would STILL take off 2m from a speaker!
*HT-5, lorra lorra gain in OD mode.
