Theory time, boyos!
I've learned a lot about wood from you guys () but I've been a bit perplexed about wood "weight" (really, density).
Assuming the same internal composition of a given species of wood and a similar conditioning/seasoning process, I assume that lighter density comes with the presence of voids in the wood. Not necessarily gaping huge defects, but microvoids within the wood polymer structure. These can be caused by the rate of growth, hence different parts of a tree will yield body blanks of different densities. There might also be something to do with mineral and sugar concentrations.
From what I've read, a lighter wood resonates more freely, but that's not necessarily a desired quality. It'll probably also have more harmonic overtones and less fundamental.
So, from a practical perspective, how would one select the proper weight of a guitar body? When buying a body from Warmoth, is it best to pick "light swamp ash" or "extra light swamp ash"? Just looking for input and nuts-and-bolts luthiery wisdom.

What do you want the guitar to be? If I'm tossing together a tele or a les Paul, I'm grabbing the heaviest fucking body I can find. Maybe it's just placebo, and I just like the feel, I dunno. On a strat, I'd be looking fir light light light.
