Martin 000-18 in Mint condition, purchased in 2025. Played sparingly (too many guitars) with no scratched or nicks. Beautiful guitar featuring spruce and mahogany, giving this guitar that wonderful midrange sound.

Making waves as one of Martin's most influential and high-fidelity acoustic body styles, the 000-18 continues to provide contemporary musicians and homebody players with traditional tone and power. Bound by tradition, Martin's Standard series acoustic guitars represent the pinnacle of golden-age acoustic guitar design, albeit equipped with an assemblage of modernized features for improved play and comfort. Potent sonics begin within the 000-18's meticulously selected spruce and mahogany tonewood formula and elite GE-scalloped X-bracing, fostering a developed yet authentic tone with plenty of room to accommodate any genre or play style. Its contemporary upgrades come in the form of complementary nickel hardware, a true bone nut and compensated bone saddle, and "Golden Era" appointments. Whether you're a fan of Martin's coveted mid-century guitar-building practices or need a new asset in your acoustic arsenal, the 000-18 is a ripe contender.

Mahogany is the tonewood of choice for countless guitarists here at Sweetwater, and spruce has been a favored top wood among guitar builders for decades. The 000-18 is armed with both, sporting a traditional solid spruce top and mahogany back and sides. This tonewood combo encourages a punchy acoustic tone that remains balanced and rich throughout any playing session. To boot, the 000-18's exclusive body style and GE-scalloped X-bracing ensure you're getting the most potent and authentic acoustic voice no matter what playing situation you may find yourself in. From casual porch picking to high-profile R&B progressions, the 000-18 is ready to provide timeless 6-string tone wherever required.

Every asset onboard the Martin 000-18 acoustic guitar enhances its impressively authentic playability and timeless yet classy appearance, from a vintage-inspired heel design to "Golden Era" top bracing. First, a look at the neck — it's made of select hardwood and features a GE Modified Low Oval profile for super-smooth navigation over every fret. Likewise, the supple 16-inch-radius ebony fingerboard with Old Style 18 inlays provides solid maneuverability while harkening back to the guitar's historic visual roots. It's all settled up with a true bone nut and compensated bone saddle combo, nickel hardware, and a gloss finish for a satisfying stage and studio appearance.

Considering the storied history of Martin’s acoustic guitar engineering and building practices, there’s no question that the company’s iconic models stand firm as the backbone of American steel-string instrument design.

The result is a comprehensive update to Martin’s most revered range of instruments, combining tonal authenticity with the comfort and versatility of a contemporary instrument. Across-the-board changes include remarkably responsive GE (Golden Era) bracing, thinner fingerboards with beveled edges, a slick vintage-style heel, angled nuts, and GE belly bridges equipped with bone or ebony bridge pins. What’s more, the refreshed standard series introduces a fresh new trio of Martin models back into the fold, including the iconic 000-17, D-17, and OM-45. Refreshed with a plethora of musician-requested features, the Standard series harnesses the power of these legendary acoustics and takes center stage once again.
