Given a choice, however, I'll take a late 40s-early 50s Gibson J-45 or Southern Jumbo (the same guitar, but with a Grand Ole Opry pimp factor). It has more of an 'Americana Sound' and you feel the low notes in your gut.
One thing that helps the sound is that the nitrocellulose lacquer finish becomes harder and thinner with age. The wood also ages more for some years, and I think all the vibrations simply loosen the guitar so it can vibrate more. All I know is, it makes a difference, and I think it makes more of a difference with mahogany soundwood than maple or rosewood. That's just my opinion.
