i'm convinced that swamp ash can be dyed successfully though not easily. of course, i'm convinced of a lot of things that aren't true. the trouble i'm having is trying to locate some scrap swamp ash to experiment on. since this is such a popular guitar wood, but apparently not used for anything else, it would seem that warmoth or some of the other folks could make scrap available for a price. i've thought about using hard ash to experiment on, but i kindda doubt it will finish the same.
