Just something to note from my experience with building 2 custom instruments with Jeff Yong. He provides some really expensive "exotic" timber to some really high end acoustic guitar builders in the US. These "exotic" wood include Monkeypod and Amboyna. You know what's the local name for these woods? Monkeypod = Rain Tree & Amboyna = Angsana.
And his source of these woods? Not from some special rainforest, but downed trees from the road side which he bought from the guys maintaining them. Same trees that line our roads in Singapore. These angsana and rain tree wood sell for more than your big leaf maple, etc in most instances too.
Also, highly prized macassar ebony? That's from Indonesia mostly, and Malaysia too.
