Much of the distinctive smell of a wood can leave the dust rather quickly. I think it has something to do with the oils and whatnot oxidizing or drying up in the smaller particles. I tried collecting a load of Brazilian rosewood dust after my last big resawing session and the magical smell was gone in just a couple days. I was hoping to make air fresheners out of the stuff
If you want a guitar to smell good, get some Port Orford or Spanish cedar on it somewhere. The PO is absurdly aromatic, the Spanish is a bit less so but still quite strong. Spruce smells nice but doesn't really hold smell as well as the cedars do and isn't nearly as strong. Maple is boring smelling to me. Most rosewoods smell good while being cut and often keep some of that when made into a guitar. Ebony smells and tastes like pepper mixed with puke...but it sure looks and feels nice!
I can get you all the ebony dust you want, anyhow. I cut most of the others, but not as regularly.
