The NRP-12 fret model captures the look and feel of an original 12 fret National Duolian. The thin-gauge steel body is highlighted by rolled "f" holes, a formed back, and period-correct, traditional ribbed coverplate. The body features a nickel rubbed finish. The mahogany neck clears 12 frets to the body and features an unbound ebony fretboard complete with mother-of-pearl position markers. Vintage-style plain tuners, ebony nut, and "National" stamped headstock complete the look of this classic.
