I can only compare two guitars. Different woods AND different builds. Both Guild dreadnoughts. The D65S is a spruce top with solid maple sides and a laminated, arched maple back. The sound is full and rich. The notes are crisp and distinct. There is a brightness to it that is very pleasant. Projection and sustain are extremely good, but with the arched back you would expect that. The DV72 is a spruce top, solid rosewood sides and back (flat) dread. Same full and rich sound, but there is a woody tone to it. Like Neal says, it has a "chimey" aspect to it, and a bit more bottom end rumble.
You can hear the difference. Don't ask me to pick one over the other. I love them both for their differences. If every guitar sounded like the other, then we'd only need one guitar. How sad would that be? I have no sound clips. :encouragement:
