A Walnut five string banjo with a 12” rim has become a popular model for us. The secondary wood, used for fretboard and trim, is often Pistachio. In this case we used some salvaged Teak from the Carpenter Ant stash in Portland. It is smooth and glassy and just hard enough for a banjo or uke fretboard. I wouldn’t buy this tropical wood new, but these salvaged scraps are fair game. The walnut is from Oregon. The skin head, non-steel strings and brass tone ring make a mellow but strong sound. A little leaf inlay with an important name wood burned into it by Nicole seals the deal.
