Re: Lightweight guitars
I think, without reviving the tonewood argument, mass DOES play a role in resonance vibration in an instrument. I believe a lower body mass is going to resonate more easily, or probably more accurate to say differently. But then at the bridge, adding a greater mass to, say, the trem block will increase sustain.
That said, there's also a bunch of other factors that play into this. I'm not sure how the chambers in a weight reduced Les Paul play into it, as the acoustics on an electric guitar aren't as big a thing. Mostly, I think it's the mass attached to the ends of the strings and the pickups that matter most. I usually think of the classical mechanics bit of an oscillating spring - but that's probably me oversimplifying it in my head.
