I've been mostly building electric guitars lately, so adding a square neck reso to the mix was a nice change.  I built a lot of resophonic guitars in the early 90's, both square and round neck. I'm a big fan of vintage Dobro guitars from the 30's. In keeping with that tradition, I still use a soundwell in my reso guitars, although much lighter with larger holes, more of a space frame than a traditional soundwell.
