From Martin’s website,

“Classic styling with a tight-waisted jumbo body shape, the J-40 is constructed from East Indian rosewood back and sides, a spruce top, and a hand-fit dovetail neck joint. It produces a tone that is beautifully balanced with powerful response and projection, enhancing the art of the singer-songwriter and session player. Boasting gold open geared tuners and Martin’s most comfortable high performance neck, this rare Martin body size has polished gloss finish and a Jumbo tone to set you apart.”
