A Bold Innovation from a Historic Brand

Martin Guitars, known for nearly two centuries of craftsmanship and forward-thinking, continues to redefine acoustic guitar design with the Grand J-28E DN. As the first doubleneck acoustic-electric to enter Martin’s Standard series in over 100 years, this instrument is a testament to the brand’s dedication to musical innovation. Combining heritage with cutting-edge engineering, Martin introduces a guitar that stands out not just for its appearance, but for its exceptional versatility and tonal breadth.

Dual Necks, Expansive Sound

The Grand J-28E DN features both 6- and 12-string necks on its expansive Grand Jumbo body, offering players a dynamic range of musical possibilities. This dual-neck setup, while visually striking, also allows seamless transitions between textures — whether moving from the brightness of 12-string arpeggios to the warmth of 6-string chords or exploring layered compositions in a live or studio setting. Because of this configuration, the instrument naturally appeals to experimental players and seasoned performers alike.

Tonewoods Crafted for Complexity

To support the guitar’s wide tonal scope, Martin luthiers chose an expertly matched combination of tonewoods. A solid spruce top drives rich projection with excellent headroom, allowing both subtle fingerpicking and vigorous strumming to ring out clearly. The East Indian rosewood back and sides contribute deep resonance and shimmering overtones. Ebony fretboards enhance the guitar’s clarity, adding a crisp, bell-like quality that holds steady across all registers, further elevating this doubleneck’s dynamic character.

Engineered for Acoustic Balance

Inside the body, Martin developed a custom doubleneck version of its renowned X Brace system. While the central “X” remains non-scalloped for stability, the surrounding tone bars are scalloped to enhance response and reduce weight. This thoughtful engineering balances tonal clarity with structural integrity. Moreover, two compound dovetail neck joints were designed to optimize weight distribution and player comfort, ensuring that this unique instrument remains practical despite its ambitious construction.

Subtle Design, Stunning Detail

Visually, the Grand J-28E DN is as refined as it is bold. It includes detailed rosette inlays, delicate binding, and precision luthiery that reflect Martin’s deep respect for traditional craftsmanship. Features such as bone nuts, compensated bone saddles, and an ebony bridge offer tuning stability and tonal consistency. Additionally, the open-gear tuners give the instrument a vintage flair, anchoring its futuristic design in timeless aesthetics.

Integrated Technology for Modern Musicians

Modern performance needs are met with a sophisticated Fishman preamp system, custom-designed for this doubleneck configuration. A 2-way toggle allows players to activate each neck’s electronics independently, supporting multiple tuning setups and offering clear tonal control on stage or in the studio. This integration makes the Grand J-28E DN not just a showpiece, but a practical tool for complex musical arrangements.
