For those who were at the talk on experiments with taking weight out, I mentioned an interesting YouTube clip someone's done using a neck-only guitar with detachable identical bodies in various woods. I said I'd post the link, which is here:
The first part covers what he has done and how and why and includes the results through a microphone (not an entirely scientific method) but 12min 40sec onwards covers all of the results, one after another, on the DAW (including the wave-forms) - by his admission, still not properly scientific but more relevant.
Clearly - and he mentions this - it is still affected by the way he plays the down chord in each case so not infallible, but interesting nonetheless.
The relevance to my talk was my own realisation (from my own experiments and off-the-wall projects) that actually, you can get SOME sort of half decent instrument simply by bolting everything to a suitably rigid neck - and that you can then take significant liberties with the body itself (in my case, taking weight out). Clearly, this guy sort of comes to a similar conclusion, albeit from a completely different direction.
