The Martin Grand J-28E DN Guitar is a breathtaking feat of engineering that brings double-neck versatility to the legendary Standard Series. For the first time in over a century, Martin has reached into its vault of innovation to create a "dyadic" masterpiece. This instrument isn't just a guitar; it is a statement piece for the modern performer.
The Legend of the Martin Grand J-28E DN Guitar
Innovation has been the lifeblood of Martin for nearly two centuries. Based in Nazareth, Pennsylvania, their luthiers spent years in research and development to perfect this specific layout. The challenge was to balance the physical weight of two necks with the acoustic integrity of a jumbo body. They succeeded by using state-of-the-art construction techniques.
Two compound dovetail neck joints ensure that the tension of eighteen strings remains perfectly distributed. This prevents the instrument from feeling "neck-heavy" during long sets. Inside, a specially modified X Brace system provides the necessary structural support. This system features a non-scalloped "X" for strength, paired with scalloped tone bars for resonance.
Premium Tonewoods for Superior Sound
The choice of materials makes this guitar a tonal powerhouse. A solid spruce top provides the "engine" of the instrument, offering massive headroom and projection. Whether you are flatpicking a folk melody or strumming heavy chords, the spruce remains articulate and clear. It handles high-velocity playing without losing its distinct character.
Complementing the top is the East Indian rosewood used for the back and sides. Rosewood is famous for its "scooped" mids and powerful bass response. In a double-neck configuration, this depth is vital. It provides a lush, cavernous warmth that fills the room. The ebony fretboards add a touch of "snap" and sustain to every single note you play.
Advanced Fishman Electronics
Playing a double-neck acoustic live can often lead to feedback or unwanted string noise. To solve this, Martin collaborated with Fishman to create a custom-engineered preamp system. This system is tailored specifically to the physical dimensions of the Grand Jumbo body. It ensures that the amplified sound is a true reflection of the natural wood.
A clever 2-way toggle switch allows you to activate the 6-string and 12-string pickups independently. This is a game-changer for recording and live use. You can tune the 12-string neck to an open drone while playing lead on the 6-string without interference. It opens a "kaleidoscopic" world of sound shaping for the creative guitarist.
Built for the Professional Stage
Every detail of this guitar is poised for high-level performance. The 12-string neck uses Martin’s time-tested profile, while the 6-string neck features a Modified Low Oval shape. Both necks have a smooth satin finish that feels fast and comfortable. This allows you to switch between necks mid-song without missing a beat or losing your grip.
