Is it safe to buy used DJ equipment?

Yes, buying used DJ equipment can be a very good option. Professional DJ gear is generally built to withstand years of use, and buying second-hand gives you access to higher-end equipment for considerably less than buying new.

But one risk is often underestimated: a unit that appears to be in good condition may have small faults that even its owner does not know about.

At Sounds Market, we regularly buy and inspect used DJ equipment before refurbishing it. In our experience, more than 50% of the equipment we buy needs some form of work.

That does not mean half the units are broken or that buying used is unsafe. Often, we are talking about adjustments, maintenance or relatively small repairs.

The important point is this: many of these problems are not apparent during a quick test and, very often, the seller does not know they exist.

The seller may be telling the truth and the equipment may still have a problem

This is probably one of the most important points when buying used DJ equipment.

When a seller says “everything works perfectly”, they are not necessarily trying to deceive you.

They may simply never have used certain functions.

We regularly encounter situations like this when buying equipment.

On a CDJ

A player can appear to work perfectly while having small problems that are hard to detect unless you know exactly what to check.

For example:

• A mini-jack connector may have poor contact.

• A Hot Cue may not respond correctly.

• PLAY or CUE buttons may work depending on exactly where you press them.

• The jog wheel may need bearing maintenance or lubrication and produce more noise than it should.

• Certain connections may have problems even though the rest of the player works correctly.

If the owner never uses Hot Cues, they are unlikely to know that one is faulty.

And if all you do before buying is connect the CDJ, load a track and press PLAY, you probably will not discover it either.

There is plenty to check on a Technics

Technics SL-1200 and SL-1210 turntables are known for their durability, but many of the units on today's second-hand market have been running for decades.

In our workshop, it is very common to need some kind of adjustment or maintenance when we buy one.

One of the things we check is pitch calibration. A turntable may run and appear to hold its speed correctly, but that does not necessarily mean the pitch is correctly calibrated throughout its range.

We also find small tonearm adjustment issues that need correcting.

Another common area is the RCA cables.

An RCA cable may carry audio perfectly while held in one position but become intermittent when moved. If you do not move the cable and check both channels during the test, you may think it is perfect.

These are small details, but they are precisely what separates checking that a unit “works” from properly assessing its condition.

The same applies to a mixer

A mixer can have even more things to check.

CUE buttons, faders, rotary controls, LINE and PHONO inputs, MASTER outputs, RCA connections, effects and dozens of other controls.

On Pioneer mixers, for example, we find problems with heavily used controls such as certain Sound Color FX buttons, the effects ON/OFF button or the LEVEL/DEPTH knob.

In some cases, relatively minor work is enough. In others, a component needs repairing or replacing.

We also encounter faulty inputs and outputs.

If you test a mixer for five minutes using only one channel and one MASTER output before buying it, much of the unit may go unchecked.

Some faults appear later

There is another kind of problem that is even harder to detect: intermittent faults.

A unit may work perfectly when you test it and start showing problems only after it has been running for a while.

It may also have previously suffered liquid ingress, damp or another incident that is not visible from the outside.

When buying privately, you cannot always establish the equipment's full history either.

It may have been opened or repaired before. The repair may be perfectly sound, or you may later discover poor workmanship that causes further problems.

All of this is difficult to detect just by looking at the exterior.

The problem with a five-minute test

This is probably the biggest risk when buying used DJ equipment.

A quick test confirms that a unit switches on and that its main functions appear to work.

But a CDJ, mixer or controller can have dozens of different buttons, rotary controls, connections, inputs and outputs.

Checking a unit properly takes time and knowing what to look for.

At Sounds Market, when refurbishing our Certified equipment, we combine tests using the diagnostic modes available on each unit with real-world operating tests.

We check the controls, then use the equipment, testing its inputs, outputs and behaviour during extended operation.

See more about our process in the guide to what refurbished DJ equipment means.

So is buying DJ equipment from a private seller risky?

Not necessarily.

You can find very well-kept equipment and sellers who know their gear thoroughly.

If you know the model well, can test it in person and the price difference justifies the risk, buying directly from another user can make a lot of sense.

The problem is assuming that “it switches on and works” means “everything is in order”.

Our own experience buying and inspecting used equipment shows that this is not always the case.

That is why the more valuable and complex the unit, the more important a thorough check before buying becomes.

The lowest price does not always mean the lowest final cost

It is also worth considering what happens if a fault appears after the purchase.

If you have bought directly from a private seller and later discover a problem, you may need to find a specialist repair service, transport the equipment, wait for a diagnosis and cover the repair cost.

Specialist DJ equipment repair services are not always easy to find. Depending on the repair and the workshop, waiting times can also be considerable.

A relatively small price saving at the time of purchase can quickly disappear if the unit later needs repairing.

That is why comparing prices should mean more than comparing two figures.

You are also comparing what is known about the unit's condition, how it has been tested and what support you will have if a problem appears later.

What does buying refurbished DJ equipment offer?

It aims to reduce precisely that uncertainty.

Professionally refurbished equipment has been inspected before being offered for sale again. If that inspection reveals a problem, it is addressed before the sale.

That does not mean refurbished equipment cannot develop a fault in the future. It is still electronic and mechanical equipment that has had a previous life.

That is why the warranty matters too.

With Sounds Market Certified, equipment is inspected by our technicians and comes with a one-year warranty.

We cannot promise a unit will never fail. What we can do is inspect it before selling it and provide support if a problem covered by the warranty appears later.
