Available for pre-order. Expected delivery Dec. 2025

For the first time in over a century, Martin is thrilled to offer a one-of-a-kind double-neck instrument – the Grand J-28E DN. As a member of the popular Standard Series lineup, this all-new guitar combines Martin’s renowned quality and craftsmanship with modern innovation, featuring an acoustic-electric with a twelve and six-string neck, giving you the versatility to explore new sounds, tunings, and musical textures all on one guitar. Its powerful gloss Grand Jumbo body delivers a bold, resonant tone, with solid East Indian rosewood back and sides and a solid spruce top that ensures balance and clarity across all playing styles. This double-neck guitar took years to perfect, and thanks to cutting-edge technology at our Nazareth factory, the Grand J-28E DN, featuring two compound dovetail neck joints and unique X bracing, is now available to the public. Both necks feature a smooth satin finish and ebony fingerboard, with the six-string neck offering a slightly slimmer profile at the nut. It also includes built-in custom Fishman® electronics, making it ready for the stage and studio. With classic 28-style appointments and endless sonic possibilities, this guitar is a dream for players seeking an extraordinary instrument that’s anything but standard.
