depends on which model you're getting
NT is alder
NT-II is maho/quilt
from what I can tell on the export website (not usa)
This would just be the NT. The USA site says Mahogany. Which site is to be trusted on this?
Whichever country you're buying it in. If you're in the USA I would go by the USA site if not in the USA I would go by the export site or if the country has a site then that one. It happens a lot of the time that the USA has slightly different models.
