I have a Yamaha FG-433s, and I love the tone of it, so I was curious to see what it was spruce. That lead me to this site, and I saw the sides were nato. I was a little confused when I looked up that wood and couldn't find jack squat, so this is my question:

Is nato some kind of "mahogany" or its own family of wood?
Okay, but does it go by a different name? I have a lot of difficulty finding any info on nato.
