From Martin:

"The Martin D-18 is one of the most iconic guitars in Martin’s lineup, trusted by legends of music and players like you for nearly a century. Known as a tried-and-true workhorse, its Dreadnought size delivers the bold, projective tone and strong bass that have shaped countless performances and recordings. Handcrafted with a solid spruce top and solid mahogany back and sides, the D-18 offers a full and balanced voice with bright trebles, a punchy midrange, and exceptional clarity in an iconic, no-frills design that has always delivered. The satin neck with a Golden Era (GE) Modified Low Oval profile, high-performance taper, and 25.4" scale length ensures unmatched comfort and playability. Elegant ebony details, including the bridge, bridge pins, and fingerboard with abalone dot inlays, complement its timeless style. Available in a variety of gloss and satin options, the D-18 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."
