You buy a used instrument safely by preparing first, asking about its history, inspecting and playing it in person, checking the serial number and provenance, paying through a protected route and putting everything in writing. For expensive or structurally tricky instruments, a specialist's look beforehand is usually worth it. The points below apply to strings, woodwinds, brass, keyboards, plucked instruments and drums alike; instrument-specific details live in the individual used-buying guides.
Preparation: need, budget and market prices
Before you scroll through listings, settle three things. What do you actually need (size, build, connectivity, playing level)? What is your budget, including what comes after the purchase (a setup or service, strings or heads, a case, possibly a repair)? And what do comparable instruments really sell for?
For the third, compare many listings of the same model and era rather than the first three hits, and remember that asking prices tend to sit above what instruments actually fetch. Our price estimate shows a range based on comparable instruments in our database; enter brand and model (optionally type and year), no sign-up needed. A simple rule of thumb: a used listing priced only slightly below new should be in nearly flawless condition, while a price far below the usual market needs a plausible reason, otherwise be suspicious.
Beginners and parents of growing children should also ask whether buying is the right route at all; for fast-growing players, renting versus buying used is a genuine trade-off.
Seller types compared
| Seller type | Advantages | Risks |
|---|---|---|
| Private seller | Often fair prices, you hear the history from the owner | Usually sold as is, returns only if agreed, fraud and theft risk |
| Dealer or shop | Inspected and often set up, advice, frequently a return policy or warranty | Higher prices, condition descriptions are sales copy |
| Auction | Prices can come out low, wide choice | No test playing, bidding fever, hard-to-verify descriptions, shipping damage |
| Classified listings | Local offers, in-person viewing possible | Fake listings, pressure to pay upfront, little protection off the platform |
Which one suits you depends on your experience. If you cannot judge an instrument confidently, a shop or an experienced companion is usually the better route, even at a somewhat higher price.
Questions to ask the seller
Ask in writing or by phone before you travel. It saves time and shows how open the seller is.
- Why is it being sold, and how long has the seller owned it?
- Any repairs, cracks, drops, modifications or refinishing? Who did the work?
- When was the last service or setup, and are there receipts?
- Where was it stored and played (house, rehearsal space, stage, garage)?
- What is included (case, accessories, original parts, paperwork)?
- Is the serial number legible, and is there a receipt from a previous owner?
Hesitant or vague answers, inconsistent details or reluctance to let you try the instrument before buying are warning signs. Long single ownership with a clear reason for selling is reassuring; a quick resale with no explanation is less so.
Storage and ownership history
Where an instrument has lived shapes its condition. Climate-controlled indoor storage beats a garage, basement or attic almost every time, because big swings in temperature and humidity make wood move and encourage corrosion and mold. Typical signs are cracks in tops or sides, lifting edges, loose glue joints, a musty smell or mildew spots in the case. For the basics, see storing instruments correctly. A cello or violin from a dry winter household needs extra attention; see humidity and cracks in cellos.
Requesting photos and videos
For distance purchases, photos and videos are your main inspection. Ask for:
- Full views of front, back and all sides in good light, unfiltered
- Close-ups of every flaw mentioned and of every repair
- The label, serial number and, where sensible, the interior (soundhole, body, drum shell, piano lid)
- A short video of the instrument being played; for electronics, powered on with all controls shown
- A photo with a handwritten note and today's date, to confirm that the seller actually holds the instrument
All images should show the same instrument. Stock photos, a different background in each picture or missing detail shots argue against buying.
Viewing and test playing
Allow enough time and, if possible, bring an experienced person such as a teacher or bandmate. Bring gear that keeps the comparison fair: your own mouthpiece or reed for winds, a tuner for guitars, your own cable and, if possible, amp for electric instruments.
- Look and smell first, before playing, in good light.
- Work every mechanism: all moving parts should operate evenly, smoothly and quietly.
- Tune and hold: does it stay in tune, and is intonation good across the range?
- Play every register: low, high, soft, loud. Buzzing, rattles, dullness or dropouts point to problems.
- Play long enough: some faults (drifting tuning, heat-related or contact problems) only show after a few minutes.
- Compare: if possible, play a similar instrument so you know what normal sounds like.
For instrument-specific checks, see the guides for the acoustic guitar, violin, saxophone, piano and drum kit.
Condition check by material group
Wood
Look for cracks, warping and open joints. Not every crack is fatal; location and length decide. A cleanly glued crack can be harmless, while an open seam in a load-bearing spot (bridge area, neck joint, edge) can be costly. Check that necks are straight, whether the top sinks or bulges, whether edges lift and whether repairs look neat. On drum shells, a smooth bearing edge and no water damage inside matter. On pianos, the pinblock and soundboard decide the instrument's fate, and you can only truly judge them with a technician.
Metal
Look for corrosion, dents, loosening solder joints and distortion. Light tarnish is normal; deep corrosion, pitting or crusty deposits inside a brass instrument are not. Dents are not automatically bad; what counts is whether they block valves, slides or keys or disturb intonation. Rust on hardware, tension rods, screws and strings (piano, harp, guitar) points to humidity or neglect.
Electronics
Does every pot, switch, jack, button and key work? Hiss, hum, crackle when turning controls, dropouts when the cable moves and scratchy knobs signal a need for service. Check through an amp or headphones while gently moving the cable. On keyboards, digital pianos and synthesizers, test every key, pedal input, display and output. Repairs to power supplies and inside devices belong with a qualified shop.
Finish and surface
Wear is normal on a played instrument and a good negotiation point. Fine lacquer checking is usually cosmetic; cracks in the wood beneath are not. Be careful with suspiciously fresh partial refinishing that may hide repairs or damage.
Mechanics
Valves, keys, slides, tuning pegs, machine heads, pedals and drum pedals must work cleanly, evenly and without slop. Sticky valves, loose key mechanisms, slipping tuners or squeaking pedals are warning signs. For any worn part, ask whether spares are still available.
Accessories, case and original parts
Be precise about what the price includes. Missing parts (mouthpieces, bows, stands, cymbal and stand parts, power adapters, pedals) can cost more later than they saved at purchase. A fitting case protects the instrument and helps resale. Original parts, packaging and paperwork (manual, warranty card, receipt) support both value and provenance. Modifications and replaced parts are not defects, but they should be disclosed; ask what is original.
Serial number, authenticity and provenance
Write down the serial number and compare it with the maker's information on location, typeface and production year. If the number does not match the model, or is ground off, covered or altered, walk away: there is hardly an innocent reason. Counterfeits often combine near-perfect logos with cheap hardware and electronics, odd details, and a price too low for the model. For expensive brands, check with the manufacturer or have the instrument authenticated; see certificates and appraisals.
Stolen gear also circulates in the used market. Warning signs include unusually low prices, time pressure, insistence on cash, no meeting at the seller's home, no documents and evasiveness about the serial number. Stolen instruments can be reclaimed by the rightful owner even if you bought in good faith. Public registries list stolen instruments by serial number, and a free lookup before buying is worth the minute. For legal questions, ask the police or a lawyer; this guide is not legal advice.
Scams and safe handling
The common schemes for online buyers in the US are well documented:
- Listings for items that do not exist: prices look reasonable, but the instrument was never there.
- The "free" or bargain instrument that must be shipped: the seller claims to have moved away and asks you to prepay shipping.
- Fake escrow or fake secure-payment sites: a link to a look-alike portal that exists only to collect your money. Genuine classified platforms do not offer such a payment service.
- Payment by wire, payment app, gift card, crypto or check: scammers like routes that are hard to reverse.
- Pressure and urgency: "other buyers are waiting", "pay now to hold it".
- Out-of-town sellers who refuse a local meeting or a phone call.
The safest approach is to meet locally, test the instrument and pay only once it is in your hands, ideally in cash in a busy public place or with a companion. For distance purchases, stay on the platform's own checkout and buyer protection, or use a reputable third-party escrow service you have found yourself rather than one the seller supplied. A credit card usually gives more recourse than a transfer or payment app, but check your issuer's terms. Insist on insured shipping and a tracking number, and film the unboxing.
Negotiating
Haggling is normal when buying used. Your strongest arguments are concrete, verifiable findings: needed repairs, missing accessories, differences from the description or comparable prices. Point out flaws calmly instead of running the instrument down. Offer a realistic price, name your reason and be ready to walk away; a buyer who sees the flaw and pays immediately has no leverage left. Go in with a firm limit.
Bill of sale and handover in writing
Put the deal in writing, including private sales. A simple bill of sale contains:
- Names and addresses of buyer and seller
- Make, model, serial number and year
- Condition, known flaws and what is included (case, accessories)
- Price, date and payment method
- A statement that the seller is the lawful owner
Collect repair and service records, and keep the listing and all messages. Many private sales are "as is", so read the terms before paying and settle open points in writing. The paperwork can also help with insurance later, see instrument insurance.
Costs after the purchase
Plan for a professional check after buying: adjustments, cleaning and replacing wear parts such as strings, heads, pads or reeds, and tuning for a piano. Prices vary widely by shop, region and instrument; get two or three quotes rather than guessing a figure. For how piano costs break down, see piano tuning. Also budget for a case, insurance and regular care.
When a professional inspection pays off
- High price, rare or old instruments and collectibles
- Cracks, warping, repairs or solder joints you cannot judge yourself
- Bowed, plucked and keyboard instruments whose condition (top, pinblock, soundboard) only specialists can assess reliably
- Doubts about authenticity, origin or originality
- Electronics with faults you cannot narrow down
Agree with the seller beforehand that an inspection before purchase is possible, and settle who pays for it. Keep in mind that repair shops also notice cosmetic improvements; ask specifically what is truly necessary for playability and value.
Common mistakes
- Saying yes too fast out of excitement and forgetting post-purchase costs
- Buying from photos alone, never playing or inspecting in person
- Judging an unfamiliar instrument without an experienced companion
- Accepting prepayment, links or unusual payment methods
- Skipping the serial number check and the paperwork
- Not clarifying accessories, case and original parts
- Underestimating repair costs, especially wood cracks and electronics
Frequently asked questions
Should I buy from a shop or privately?
If you cannot assess the instrument yourself, a shop with advice and a return policy is often the calmer choice. Buying privately can save money, but you carry more risk.
May I have an instrument inspected before buying?
It is common, and honest sellers usually do not mind. Raise it up front. A seller who refuses is giving you a reason for caution.
Is a scratch in the finish a problem?
Usually only cosmetic and a point for negotiation. What matters are cracks in the wood, warping and function.
How do I spot a counterfeit?
Compare serial number, logo, workmanship and hardware with the maker's information; an unusually low price and missing paperwork are further hints. If in doubt, have it authenticated.
How do I pay safely?
Preferably in cash at an in-person handover, otherwise through the platform's own protected checkout. Never prepay strangers and never use wire transfers, gift cards or crypto.
