Re: Highest quality wood for good acoustic tone
Solid Sitka or Engleman spruce top, solid rosewood back, with mahogany neck and either a rosewood or ebony fretboard. That combination, IMO, is the best
I'm starting to like Cedar tops on Mahogany backs as well, like some of the Taylors.
Most rosewood nowadays is Indian Rosewood, and I've come to love it's tone more than mahogany backs. Mahogany is brighter and punchier, but Indian Rosewood is punchy and warm and bigger sounding.
