Step-by-Step Guide (9 Steps)

1. 1

   Set Your Budget and Choose a Body Size

   Under $250 used: decent laminate-top beginners (Yamaha FG800, Fender CD-60S, Seagull S6). $250–$600: excellent mid-range instruments with solid tops (Taylor Academy, Yamaha LL series, Seagull Artist). $600–$1,500: professional-grade used acoustics (Martin 000-15M, Taylor 314ce, Gibson J-45). Over $1,500: premium and vintage territory (Martin HD-28, Taylor 814ce, pre-war instruments). Body size affects sound and comfort: Dreadnought (big, loud, strumming-focused), OM/000 (balanced, fingerpicking-friendly), Concert/Grand Concert (smaller and tighter for recording), Jumbo (loudest, most projection).

   For fingerpicking and solo playing, an OM or 000-size guitar is generally more responsive and balanced. For strumming and rhythm playing, a dreadnought projects better with a fuller low end.

2. 2

   Understand Solid vs. Laminate Tops

   Solid-top acoustic guitars improve in tone as they age — the wood loosens up and becomes more resonant over time. Laminate (plywood) tops don't improve and don't sound as rich, but they resist humidity damage better. For any guitar over $300, insist on a solid top. How to tell: look inside through the soundhole with a flashlight at the edge where the top meets the side — solid tops show a single line of grain, laminate shows multiple thin layers like plywood. All-solid construction (solid top, sides, and back) is the benchmark for instruments over $800.

   Some sellers call their guitar "solid top" without knowing whether it actually is. "Solid body" (electric guitar term) and "solid top" (acoustic) are different things. When in doubt, look inside.

3. 3

   Inspect the Top for Cracks and Damage

   The soundboard (top) is the heart of an acoustic guitar. Inspect every inch: look for hairline cracks radiating from the soundhole, cracks along the grain lines (especially under the treble side of the bridge), and finish checking (a network of fine cracks in the finish — normal on older lacquer, not alarming). Repaired cracks are acceptable if done by a luthier — look inside the guitar through the soundhole for cleats (small rectangular wood pieces glued across a crack to stabilize it). Unrepaired cracks on the top are a structural issue. A crack in the lower bout or along the grain near the bridge is more serious than one near the soundhole.

   A crack near the heel joint (where the neck joins the body) on any acoustic guitar is a serious structural defect. Neck joint repairs can cost $300–$600+. Do not pay more than scrap value for a guitar with an unrepaired heel crack.

4. 4

   Check for Bridge Lift

   Bridge lift (the bridge pulling away from the top) is one of the most common acoustic guitar problems. It happens due to heat, humidity, and normal string tension over time. To check in listing photos: look at the back edge of the bridge (the edge furthest from the soundhole) — there should be zero gap between the bridge and the top. A gap of even 1mm indicates lift. Minor lift is a $100–$200 repair. Significant lift (visible gap across the full bridge) can require bridge removal and regluing, which adds $200–$400. Factor this into your offer price or pass on the guitar entirely for anything over 2mm lift.

   Ask sellers specifically: "Is there any bridge lift on this guitar?" — it's a specific, clear question that serious sellers will answer truthfully.

5. 5

   Evaluate the Neck, Action, and Frets

   Sight down the neck from the headstock: it should be straight or have very slight forward bow (relief). Check the action (string height) at the 12th fret — acoustic guitar ideal action is 7/64" (low E) and 5/64" (high E). High action can often be corrected with a saddle lowering ($30–$60) or full setup ($75–$100). Ask the seller the 12th fret action numbers. Also check the neck angle: an acoustic guitar neck should point at the top of the saddle (not the bottom). A neck set is an expensive repair ($400–$800 at most shops) but extends a guitar's playable life by decades — older quality acoustics often need one.

   A guitar with high action that is otherwise in excellent condition is often a great deal — it just needs a setup. Budget $75–$100 for this and factor it into your offer.

6. 6

   Inspect the Bracing and Interior

   Use a flashlight through the soundhole to inspect the interior. What you're looking for: loose bracing (the internal wood supports glued to the top and back — a loose brace buzzes when played and costs $75–$150 to repair), evidence of cleats (repairs — acceptable if done by a luthier), moisture damage (white haze, warped wood), and general condition. A pristine interior on a 30-year-old guitar is a positive sign of careful ownership. Bracing style matters on vintage guitars: Martin X-bracing, scalloped bracing, and non-scalloped bracing all produce different tones and have different collector values.

7. 7

   Check Tuning Machines and Nut

   Acoustic guitar tuning machines should turn smoothly with no slipping. Older Grover Rotomatic tuners are reliable workhorses. Waverly and Gotoh tuners are premium options often found on higher-end guitars. Plastic tuner buttons crack and yellow with age — not a functional issue but a visible one. The nut (at the headstock end of the fretboard) should have proper slot depth: strings should sit half in the slot. Too deep (strings buzz on open) and too shallow (strings don't seat properly and intonation suffers) both cost $30–$60 to fix.

8. 8

   Research the Serial Number and Provenance

   For any guitar over $400, verify the serial number matches the claimed production era. Martin, Taylor, Gibson, Yamaha, and other major brands have well-documented serial number databases. Use Treblemakers' serial number decoder (/tools/serial-number-decoder) or the manufacturer's registry. For vintage Martins, a 1969 D-28 is a completely different instrument from a 2010 D-28 — the serial number is the only reliable way to verify. Sellers who can't provide a serial number for a claimed-vintage guitar should be approached with caution.

   Fake "vintage" acoustics are less common than fake electric guitars but do exist. Any guitar claimed to be pre-1970 should have a serial number verified against a manufacturer registry and ideally an independent appraisal for values over $1,500.

9. 9

   Test the Sound and Playability on Arrival

   Tune the guitar and let it acclimate for 30 minutes if it arrived cold. Play every fret on every string — listen for buzzing, dead notes, and intonation issues. Strum open chords and listen: a good acoustic should ring clearly with sustain. Fret notes at the 12th fret and compare them to the same open string — they should be exactly one octave apart (check with a tuner). If they're sharp, the saddle may need to be adjusted. Return windows on Reverb (7 days) and eBay (30 days) apply if the guitar doesn't match its description.

   New strings dramatically improve a used acoustic's tone and playability. Change them when the guitar arrives — a $10 set of acoustic strings is one of the best investments in a new-to-you guitar.
