Two necks, one foundation, ample sonic possibilities

Available now at Sadek Music, the Martin Grand J-28E DN embodies a masterful balance of tonewoods and craftsmanship designed to explore vast sonic dimensions. Considering the complex tonal territory this doubleneck is built to traverse, Martin’s expert luthiers selected tonewoods that support its expanded scope with detail, depth, and character. A solid Sitka spruce top delivers immense projection across a wide dynamic range, maintaining exceptional headroom and strong fundamentals that excel in strumming, flatpicking, or fingerpicking — from gentle textures to full-bodied voicing. The East Indian rosewood back and sides enhance the spruce’s clarity with cavernous warmth and powerful low-end resonance, adding richness to every note. Completing this tonal foundation, ebony fretboards on both necks provide relentless sustain, bell-like transparency, and crystalline presence that shines across every register.

Years of R&D, straight out of Nazareth

Years of development at Martin’s Nazareth facility is what finally gave birth to the Grand J-28E DN, thanks to a slew of state-of-the-art technologies that were methodically refined to guarantee this doubleneck guitar would make the Standard series’ 100-plus-years of waiting worth it. Two compound dovetail neck joints were carefully shaped and placed to balance weight distribution, sonic presence, and comfortable accessibility. Inside the Grand Jumbo, a cutting-edge, doubleneck iteration of Martin’s X Brace system was developed to support the physical and acoustic demands of such a wide-ranging instrument. The “X” portion, itself, is non-scalloped, however . However, the scalloped tone bars aid in mitigating weight and sound issues, in addition to augmenting projection and honing your low-end, guaranteeing detailed, dynamic voicing across the spectrum.

Custom-engineered Fishman dual-neck dynamics

The Martin Grand J-28E DN, available now at Sadek Music, redefines acoustic-electric versatility with its custom-engineered Fishman dual-neck electronics. While the 6- and 12-string doubleneck design already offers boundless tuning and tonal possibilities, Martin takes it further by partnering with Fishman to craft a preamp system tailored specifically for the Grand J-28E DN’s unique acoustic structure. Inside the body, a 2-way switch allows players to independently engage either the 6-string or 12-string pickup, unlocking a vast tonal palette and eliminating unwanted resonance-based dissonance when alternating between tunings. This bespoke Fishman system ensures pristine clarity, natural acoustic warmth, and balanced dynamics across both necks — making the Grand J-28E DN a true masterpiece of dual-neck design and sound innovation.

Poised for performance

From long-haul studio sessions to all-night stage style, the Martin Grand J-28E was designed to command the eyes and ears of everyone around you, and Martin’s spared no effort to ensure you’re primed to put on your best performances. A sonorous ebony bridge and nickel open-gear tuners give you unrivaled sonic stability, while two bone nuts, alongside a compensated bone saddle, culminate in remarkable intonation and sustain. Martin’s time-tested 12-string profile is joined by the 6-string neck’s Modified Low Oval profile, each supplying tailored comfort and control of the satin-finished necks’ respective dexterity demands. Style 28 inlays adorn each fingerboard, both of which boast a 16-inch radius that deftly supports your aural exploration across the 20 frets that sprawl a 25.4-inch scale.
