It's amazing how a simple thing as glue makes some responders become 'unglued'. The fear of lack of resonancy with glued wood causing poor tone, pales in comparison with all the other factors. Pickups, strings, electronics, amps, playing ability (I would wager EC could make the cheapiest store guitar sound great, I could make the most expensive setup sound bad LOL) etc. The most important factor of glue is that it effectively bonds the pieces of wood together. You don't want to be holding a bundle of wood if the glue fails.
