With a lower bout 11.25", a body length of 16", and a scale of 21.4", the 5-21 is the smallest guitar in Martin catalogs. These guitars were originally categorized as “terz” guitars, designed to be tuned to three frets higher than standard pitch.  This particular example features a Spruce top over a Brazilian Rosewood back and sides.  The back and sides have been oversprayed, a section of the binding replaced, and the neck has been reset. Comes with the original Hard Case.
