National Thunderbox M-14T Revolver Resophonic Guitar


Instrument Categories: , ,

The National Thunderbox M-14T in the Revolver finish came through the door, sporting a dark brown ‘Revolver’ finish on the deeper body. National’s ‘Denim’ finish is also available. This example is one of the very few currently available as new anywhere.

The National Thunderbox M-14T is the latest version of National’s standard M-14. The newly improved National Thunderbox M-14T features a 4″ deep body, improving the low end response and creating a louder, punchier instrument. The National Thunderbox body is composed of laminate top and back, and solid mahogany sides. This instrument also features a mahogany neck, ebony fretboard and mother-of-pearl position markers.

This exceptional instrument is brand new, and a National hardshell case is included. This specific guitar is product number 126.

Here’s the builder on the National Thunderbox M14T: 

“Thunderbox” is the perfect description for the big, powerful voice of the M-14T. That booming sound originates from the M-14’s mahogany body, composed of a laminated top and back combined with solid sides. But with its thicker, four-inch-deep body, the Thunderbox speaks with authority. It’s improved low-end response combined with the singing high-end tone creates a louder, punchier guitar that truly projects. The mahogany neck is capped by an ebony fretboard and mother-of-pearl position markers.”
