What woods are you referring to? Maple, ash, alder, spruce, cedar are all US or Canadian woods. But there are very few exotic US hardwoods other than walnut and cherry.

I guess what I meant was why can't they use "exclusively" American grown wood. Not importing rosewood, ebony, korina or mahogany for example and using something grown here instead. Do walnut or cherry not make good instrument wood? I've heard of people making guitars out of oak,elm,birch and sycamore but I would think the oak would be heavy.
