1930's National Triolian in original "Brown" polychrome finish! During the Great Depression the single cone, steel bodied Triolian was instrumental in offering loud volume and great tone at a good price. They were especially popular among blues musicians like Son House and Bukka White who could fill a whole juke joint with just resonator and their voice. It features a steel body, flat cut F holes, and a 12-fret maple neck with bound fingerboard. The original tuners have been changes to modern three-on-a-plate Kluson machines, and the tailpiece has been changed to a modern chrome part, comes with a hardshell case!
