From Martin's website,

"

The Martin HD-28E is a legendary acoustic guitar, trusted by generations of players and played by countless icons across genres. Its Dreadnought body size and scalloped bracing delivers the bold, projective tone with strong bass, clear trebles, and rich overtones that has defined acoustic music for nearly a century. Handcrafted with a solid spruce top and solid East Indian rosewood back and sides, the HD-28E offers a resonant, balanced voice for all playing styles. Bold herringbone top inlay and an ebony fingerboard with abalone diamond and square inlays add a vintage-inspired touch. The satin neck, featuring a Golden Era (GE) Modified Low Oval profile, high-performance taper, and 25.4" scale length, ensures effortless playability. Complete with antique white binding, an ebony bridge with bone pins, nickel open gear tuners, and Fishman Aura VT Blend or LR Baggs Anthem electronics, the HD-28E is a guitar you can trust to unleash the artist within. 

Martin’s refreshed Standard Series for 2025 enhances tone, comfort, and style. Sitka spruce GE top bracing, as featured on the Modern Deluxe Series, delivers vintage-inspired tone and sustain, while updates like a reimagined neck profile, thinner fingerboard, and refined bridge and heel improve playability and aesthetics. Each guitar includes a hardshell case."
