How to Shop for a Used Instrument

The savings are real if you bring a checklist — six moves anyone can make

Musical instruments are one of the most normal second-hand categories: they hold value well, many owners upgrade within a year or two, and older instruments are often underpriced. But "cheap" does not automatically become "a good deal" — a checklist does that.

What suits buying used

Good fit: simple, standardised instruments — guitars, digital pianos, most winds, violins (plenty of stock).
Care needed: instruments dominated by wear parts (reeds), ageing electronics (old synths), and anything needing expert appraisal (old acoustic pianos — bring a tuner).

Six moves anyone can make

1. Look in daylight: flaws cannot hide in good light. 2. Play your try-out pieces (three below): listen for — any buzz, even volume across notes, harsh highs. 3. Check for physical damage: on guitars, sight down the neck and check the bridge; on winds, dents and hardened pads; on strings, cracks (hold against the light). 4. Read the wear: fret dents, key wear, the patina — how long it served is more honest than the seller's story. 5. Verify the serial number: match it against receipts; walk away from cheap-without-papers (it may be stolen). 6. Anchor the price: look up recent sold prices for the same model, compare three — never anchor on "new" price.

Preparing "try-out pieces"

Bring three to the viewing (even as phone recordings):

a solo passage — exposes intonation and action;
a study — tests evenness across the range;
music you love — it will tell you whether you really want to take it home.

Two "don'ts" at the transaction

Do not pay untested (not even same-city delivery);
Do not pay for "stories" (whose teacher owned it does not matter — only condition and price).

Listen: a "clean" fifth

Intonation can be checked by ear: a good perfect fifth sounds clean — two notes fused. The example below is the standard; bring it with you and compare on site.

One of the most common second-hand categories: the classical guitar.
Strings are worth the hunt: how to read the condition of a violin.
What "in tune" is measured against: Concert Pitch.
