Martin CMD182025 Standard Series D-18 Acoustic Guitar - Natural

Martin D-18: A Legacy of Timeless Tone Available at Sadek Music, the Martin D-18 remains one of the most influential and genre-defying acoustic guitars ever crafted. First released in 1931, this iconic model has undergone numerous refinements over nearly a century to meet the evolving demands of musicians. The refreshed Standard Series D-18 revisits its most cherished vintage era while incorporating modern, performance-focused enhancements. The solid Sitka spruce top features GE-scalloped, forward-shifted X-bracing, maximizing responsiveness and delivering a lively, resonant feel. Mahogany sides provide a warm, punchy, and bass-rich voice that cuts through bluegrass ensembles and fills out rock, country, and pop mixes. The GE Modified Low Oval neck with a 1.75-inch nut width ensures fast, comfortable playability for flatpickers, fingerstyle players, and casual strummers alike. Additional Standard Series upgrades, including a thinner beveled ebony fingerboard and vintage-style heel, further enhance this revered design. The refreshed Martin D-18, available exclusively at Sadek Music, continues to uphold its legacy as one of the most treasured and time-tested 6-string guitars in the world.

Savor the Sound of Solid Mahogany

Available at Sadek Music, the Martin D-18 delivers a warm, punchy voice that has graced countless recordings across genres since its 1931 debut. Even if you haven’t played one, its tone is likely familiar — the D-18 has been a cornerstone of 20th-century guitar music. The refreshed D-18 features a Sitka spruce top supported by GE-scalloped, forward-shifted X-bracing, capturing the ultra-responsive feel and rich low-end power that have made Martin’s prewar models highly coveted. Mahogany back and sides focus on the fundamentals of each note, offering a clear, direct tone in contrast to the harmonic-rich rosewood of the D-28. This tonal combination has made the Martin D-18 one of the most enduring and versatile steel-string guitars in history — a longtime favorite of bluegrass pickers, rock strummers, country players, and musicians across virtually every acoustic-driven genre, now available at Sadek Music.

Setting the standard for steel strings everywhere

If there were such a thing as a “standard” acoustic guitar shape, it would undoubtedly be the dreadnought. It’s Martin’s most iconic model and a key component to the cannon-like projection and booming bass response that’s defined the Nazareth sound since the D-18 and D-28 appeared in the early 1930s — and even earlier if you count Martin’s “Ditson” models! Whether you’re a flatpicking bluegrass phenom or a singer/songwriter strummer, a Martin dreadnought will provide you with a lifetime’s worth of superior steel-string tone.

Standard Series: Revisiting Timeless Martin Tradition

Available at Sadek Music, Martin’s refreshed Standard Series celebrates the company’s storied history of acoustic guitar craftsmanship. Recognized as the backbone of American steel-string guitar design, Martin’s iconic models now receive a thoughtful update that revives the look and tone of the brand’s golden-era vintage instruments while integrating modern performance enhancements. Across the series, changes include GE (Golden Era) bracing for remarkable responsiveness, thinner fingerboards with beveled edges, a vintage-style heel, angled nuts, and GE belly bridges with bone or ebony pins. The refreshed Standard Series also reintroduces a trio of legendary models — 000-17, D-17, and OM-45 — now equipped with musician-requested features that combine tonal authenticity with the comfort and versatility of a contemporary instrument. The Martin Standard Series, exclusively available at Sadek Music, harnesses the power of these legendary acoustics and keeps them center stage for a new generation of players.
