I am carrying lots of maple classical guitars these days made by both Spanish and German makers. As of January 2nd this year, all species of rosewood (dabergia family) have been listed as endangered species, and so require CITES licenses to import and export. The costs in time and grief of obtaining CITES licenses adds significantly to costs of guitars, so makers are scrambling to find alternative woods. Maple, of course, has a very long history as a fine wood for guitar making-- and was very popular during the 19th century for classical guitars.
