Anyone ever thought of using bois d' arc (I pronounce it Bodark) in an instrument? We also call them "Horse Apple Trees" because of these nasty green fruit things that grow on them. There's tons of it growing in east texas. The wood is hard as a rock and has really cool looking yellow streaks running through it. Seems like it would make a really nice body. I don't know anything about the properties of the wood. I just know I've tried cutting one down with an axe and it feels like hitting concrete with an aluminium baseball bat.
