Buying Guide: What to Know Before You Buy a Used Martin Acoustic Guitar
Martin models and series from the 1980s to today
Martin’s lineup is organized by body size and by series. The dreadnought (D-18, D-28) is the best-known shape, with a big voice that suits strumming and flatpicking. The OM and 000 bodies are smaller and favored by fingerstyle players for their balance and clarity. Within each size, the Standard Series is Martin’s core line, the Authentic Series and Golden Era reissues replicate specific vintage-year specs, and Custom Shop and limited-edition models add special woods, appointments, and artist signatures, such as the 000-28EC Eric Clapton model. Martin’s X Series uses high-pressure laminate construction for a lower price, so confirm the model of any guitar you’re considering.
What drives value in a used Martin
-
Model and series — Authentic Series, Custom Shop, and limited-edition guitars generally hold their value best.
-
Wood — solid Sitka or Adirondack spruce tops and rosewood or mahogany back and sides drive both tone and price, and guitars with Brazilian rosewood command a premium.
-
Originality vs. modification — an unmodified guitar is generally worth more than one with replaced tuners or a non-original finish, though a tasteful pickup installation can add practical value for a working musician.
-
Repair history — neck resets and refrets are routine on a played guitar and don’t necessarily hurt value if done well; top cracks and brace repairs should be disclosed and assessed for stability.
-
Case and paperwork — the original hard case and any documentation add value and help with resale.
How we grade and document our guitars
Every Martin in this collection is inspected in-house before listing. We verify serial numbers against Martin’s production records, note any repairs or non-original components clearly in the listing, and photograph construction details so you can evaluate condition and authenticity before buying. Every guitar also receives a professional setup before it ships.
Frequently Asked Questions
How do I find out when my Martin was made?
Martin has numbered its guitars consecutively for well over a century, and the serial number is stamped on the neck block, visible through the soundhole. Match it against Martin’s published serial number list to find the production year. You can use our Dating Your Guitar guide for help, or contact us and we’ll lend a hand.
What’s the difference between a D-28, a D-18, and a 000?
The D-28 and D-18 are both dreadnoughts. The D-28 uses rosewood back and sides for a deeper, richer sound, while the D-18 uses mahogany for a drier, more focused tone. The 000 is a smaller body that many fingerstyle players prefer for its balance and comfort. The OM, or orchestra model, shares that smaller body with a longer scale length.
Do used Martins need special care?
Solid-wood guitars are sensitive to humidity. Keeping a Martin in its case with a humidifier in dry weather helps prevent cracks and a dropped top, and we recommend a professional setup after any big change in climate.
Do you ship used guitars internationally, and how are they insured?
Yes, we ship internationally, and every instrument is insured in transit and packed to protect it from damage. Import duties and taxes are the buyer’s responsibility and vary by destination country. Guitars with regulated tonewoods such as Brazilian rosewood may require additional documentation for international shipments.
Can I trade my current guitar toward a used Martin?
Yes, we accept trades toward guitars in our inventory. Send us details and photos of your guitar and we’ll provide a trade valuation. You can use our Sell My Vintage Guitar form to make it super easy.
