All the wood has to do is remain stable and keeps the important parts in the right places. I don't believe it makes any difference to the sound at all, Strings, pick ups, bridge and technique do, though.

I disagree. I have two parts built Precisions, both with identical Allparts maple necks, both with Fender "Original" replacement pickups with identical pots, wiring and capacitors, both with identical gotoh 201 bridges, both with identical Fender round wounds on of the same age and amount of usage/wear. One has an Alder Fender repacement MIM body, the other a Red Meranti body. Both are set up exactly the same in relation to action and pickup height. But oddly they DON'T sound identical. The Meranti bodied one sounds a lot brighter and more resonant than the Alder body. If it was just me picking this up I'd say it was imagination, but it has been commented on by my Guitarist many times.
