When I was making normal single sides guitars I made a couple with Osage orange and I thought they were superb. It's a first rate tonewood from a sonic perspective. The down side is few customers want an orange/yellow with a hint of green guitar.
A pal of mine in the trade, A.J. Lucas has a reputation for using non traditional woods and non exotics, so a passed the remaining sets I had onto him.
