I dont think its a good idea to do that , i have seen guitars with the grain running (not completely perpendicular) but somewhat and built some of my own like that.> and yes usaf1989 burl (grain going everywhere) but does it sound GOOD???? (thats up to you) anyway take a square piece of wood about oh .100 thick 4" square (and break it with your hands) in both grain directions (whats easier) get what im saying (now put that under average 150 lbs of string pressure) say over a 10 year span. So usaf1989 saying QUOTE:String tension acting across the grain vs. with the grain shouldn't be a huge deal, either. is not good advice. (im not trying to bash anyone) but being a cabinet maker and instrument maker are Two worlds apart. Fryovanni and Setch have very good reasons NOT!! to do it too!!
(I miss burl ives)
