Hi bandsound31, The sound of a guitar that's been constantly played for 30 years is more resonant (open) than the same guitar that's been played for 10 years and even more so than the same guitar played for 2 years. The molecules in the wood becomes loose when vibrations "sink" into the wood. Of course, playing the guitar is the best way to give the wood molecules the "Good vibrations". So, play on, play on, and play on! The more you play it, the better it sounds, until the end of the world. *Sorry, I can't tyle Chinese.
