Great comments! Now I've got another question: I was interested in the comment that described how a guitar that hadn't been played for a while improved its tone simply by being played...like an amazing bottle of wine I had once that that magically changed its drinkability in the manner of an hour or so, simply by being left open to react with the air. Can anyone describe the science of what happens when a guitar is played - as opposed to being left in the case - that causes the tone to change/improve?
