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.
