Available in steel, brass, and German silver each guitar features a hardrock maple neck and a chicken-foot resonator coverplate. 12-Fret models have a slotted headstock and flat-cut F-holes while 14-Fret models have a peghead and rolled F-holes. Steel models, like all National steel bodied instruments, have an interior finish to protect against rusting. Also available in Tricone models.
