As I develop the finish on the current build, I am contemplating an all Catalpa build. I did one a few years ago and the sound is amazingly top drawer. It is certainly more "normal" sounding than any other all hardwood guitar I've made. The guy who owns it has a decent collection, including other samples of my work. While he may have changed his mind, he has several times told me that the all-Catalpa ("Blondie", to him) is his favorite player. If I do another one, I plan to stain all but the top with the Pernambuco juice. Here is a sample board I made today with 1, 2, 3, and 4 coats of stain under a single coat of varnish (so far).
