Wood, just to follow up on Lal's post, is more of a tone modifier than a end all, be all of tone, even within a given species some trees will yield a better sounding plank, I think clarity of the the grain and density account for that and their seems to be some evidence for it, but, one thing I think we should always remember is that guitars are the sum of all their parts, good wood has to be mated with equally as good construction and hardware or it is just wasted..........................
