Buying a used digital piano: classifieds, dealers or refurbished – the big guide

The used market for digital pianos is huge, fair and surprisingly safe – once you understand three things: the difference between buying privately and from a dealer, the handful of warning signs in classified ads, and what a well-kept instrument fairly costs. That is exactly what this guide covers. For used acoustic pianos (pin block, soundboard & co.) there is a separate viewing guide.

Why buying used almost always works with digital pianos

A digital piano has no strings to rust and no felt for moths to eat. Hammer actions age slowly, the electronics usually last decades – and the sound engine of a five-year-old mid-range model is as good today as on day one. At the same time, digital pianos lose market value quickly, like all electronics: well-kept portables typically cost 30–40 % less used than new, with 90 % of their lifespan still ahead of them. That is why we list the evergreens from Yamaha, Kawai, Roland, Casio and Korg as ♻️ used classics in our catalogue – with honest market ranges and what to check on each model.

Private or dealer? The difference that matters most

This question decides less about the price than about your safety net:

Private purchase (classifieds, eBay from private sellers): usually cheapest – but private sellers normally exclude liability for defects (“sold as seen”). Whatever you miss while trying it out is your problem afterwards. That makes the checklist below not a nice extra but your only protection.

Dealer purchase (used department, refurbished stock, B-stock): somewhat more expensive, but with a statutory warranty – at least one year even on used goods in the EU – and often a return right. If you cannot or do not want to inspect an instrument yourself, this is the most relaxed route to buying used.

Refurbished instruments, B-stock and returns

Between “new” and “privately used” lies an often overlooked middle world: large music retailers sell customer returns and showroom pieces as B-stock – technically flawless, at most with tiny cosmetic marks, with full warranty and 5–15 % below the new price depending on the shop. Some dealers also run a genuine used department with bought-in, inspected instruments. For cabinet digital pianos and hybrids it is worth asking about refurbished instruments: action checked, wear parts replaced – essentially a factory service for the digital world. Just remember: the checklist still applies, because “refurbished” is not a protected term. Ask specifically what was done.

The classified-ad checklist for the viewing

Ten minutes that prevent a bad buy – best taken along printed out:

☐ Play every single key, quietly and loudly: same weight, same volume, nothing rattles, sticks or hangs? Dead or double-triggering keys are the most common age problem.
☐ Test all connections: both headphone jacks (crackling? loose contact?), USB/MIDI ideally briefly with your phone, pedal input, power socket (does it wobble?).
☐ Speakers at high volume: does anything buzz or distort – especially in the bass?
☐ Press and hold the pedal(s): does half-pedalling work (where supported), without clicking?
☐ Cabinet and location history: you can smell a smoker's household and see water marks. For cabinet pianos: does it stand level, does anything wobble?
☐ Original accessories: power supply (the right one!), music rest, pedal, manual. A missing proprietary power supply costs 20–40 € – a bargaining point.
☐ Note the serial number/build year and cross-check at home – also against the build years on our ♻️ model pages.
☐ Factory reset: have it performed – it reveals whether settings were masking problems.

Recognising scams – the five classics

Digital pianos are a popular field for ad fraud because the prices are high enough. These patterns end the purchase immediately:

1. Clearly too cheap: a two-year-old brand instrument at half the usual used range has a reason – usually it does not exist.
2. Shipping only, no viewing: “Abroad for work, a forwarder will deliver.” A classic. A real 12 kg portable can always be collected as well.
3. Advance payment to strangers: bank transfer or PayPal “Friends & Family” to unknown people = money gone. Pay cash on collection; for genuine shipping only with buyer protection.
4. Photos from the internet: manufacturer images instead of own photos. Ask for a photo with a note (“name + today's date”) – scammers drop out here.
5. Pressure and haste: “Three other buyers, decide today!” A serious seller lets you check in peace.

What is a fair price?

For the common classics you do not have to guess: our ♻️ used-classic pages give an honest market range per model (kept up to date) plus build years and the model-specific weak spots. Rough guidance beyond that: well-kept standard portables 30–40 % below the last new price; very popular models hold their value better; cabinet instruments lose more because of transport. Every defect from the checklist – missing power supply, cleaning due, crackling jack – is a factual bargaining point.

Transport: the underestimated detail

A portable (10–15 kg) travels on the back seat. A cabinet digital piano (40–80 kg) needs two people, blankets and a suitable car – factor that in before driving 200 km to a bargain. Hybrids and digital grands belong in professional hands, like acoustic instruments; more in the moving guide.
