National M14 Fret Thunderbox Revolver 2025

National's M14 Thunderbox Revolver pairs the warmth of an all-mahogany body with the unmistakable midrange tonality of a great resonator guitar.

"Thunderbox" is the perfect description for the big, powerful voice of the M14T. That booming sound originates from the M14's mahogany body, made from a laminated top and back combined with solid sides, and with its thicker, four-inch-deep body the Thunderbox truly speaks with authority.

Its improved low-end response, combined with a singing high-end, makes for a louder, punchier guitar that really projects. The mahogany neck is capped with an ebony fingerboard and mother-of-pearl position markers, finished off with the striking Revolver satin finish.

This example is used but in near-mint condition, with only a tiny ding on the top and another near the truss rod adjustment. It comes complete with a hardshell case, a polishing cloth and a TFOA Passport.

This instrument has been carefully inspected for condition and playability, then set up to our Gold Standard by a luthier. We make sure it arrives in your hands exactly as it should: sounding its best, playing effortlessly and ready to be enjoyed from the very first note.
