Let’s discuss one of the most important subjects every guitarist needs to know in order to troubleshoot their electronics: testing pickups with a multimeter. As a guitarist, you are constantly looking for a better tone.
You often try various pedals, amps, and strings, among others. One thing you don’t meddle with, though, is the pickups, mostly because they are quite terrifying in the first place.
In essence, your electric guitar won’t function without a pickup. So, if you are experiencing technical difficulties such as hum, buzz, or even no sound, you might be wondering how to test if your pickup is working.
Here, we’ll discuss a few common techniques that guitarists may use to test their electronics with a multimeter. You’ll fully understand how to test guitar pickups with a multimeter by the conclusion of this article.
What is a Guitar Pickup? How Are They Made?
A guitar pickup A series of magnets wrapped repeatedly in coils of insulated copper wire. A magnetic field is created around the strings as a result of the copper wire coil’s operation. Each time the strings vibrate, a voltage is also generated. After passing through the equipment and wires, it emerges as sound from your amplifier.
Typically, a piece of plastic or fiberboard is used as the foundation for the pickup building process by guitar manufacturers. Six circular holes were punched out of the plastic, which is also known as flatwork, with the intention of holding pole components. These are iron metal cylinders with a bar magnet beneath that are used as cylindrical magnets.
Carefully placed away from one another, the magnets mimic the spacing between guitar strings. Typically, a magnet wire that is protected by a thin coat of varnish is wrapped repeatedly around the magnetic structure. A coil with scatter-wrapped wire generates a crisper sound than one with smooth-wound wire.
How To Test Guitar Pickups With Multimeter
Test your pickup with a multimeter to get a good idea of its condition and whether your guitar’s tone is wrong or it has abruptly ceased working.
If the pickup you want to test is already installed on your instrument, you can do so via the output jack.
Looking to Buy a Multimeter?
Do check some picks and recommendations by our expert team:
To use a multimeter to test your pickup, follow these steps:
- The multimeter should be set to 20K ohms. Turn the dial to access this choice.
- Do not connect your guitar’s amp cord to your amplifier. The cable’s free end should be found to measure resistance.
- Set your guitar’s tone and loudness to its maximum potential. The test won’t produce valid results if you accidentally turned the volume down.
- If your instrument has more than one pickup, choose the one you wish to try. You should test your guitar’s two or three pickups.
- Attach the multimeter probes to the guitar cord you already plugged in. The cable’s sleeve is attached to one multimeter probe and the cable. You will receive a reading from the multimeter. The resistance of your pickup is measured here.
Before measuring resistance, make sure the range on your multimeter is set correctly. The standard range for multimeters is 20K ohm, although there are many different types available; read your handbook to be sure this is the case. You will obtain an inaccurate reading if you choose the incorrect range.
Let’s suppose you want to buy a multimeter but don’t already have one. You can get Multimeter with Ohm Volt Amp Tester in such instances).
It is a high-speed digital multimeter with an integrated LCD backlight. You can precisely estimate your pickup’s resistance with the aid of this multimeter, which is simple to use. It is also extremely safe because of the silicone cover’s protection from electric shock and the double ceramic fuse’s ability to prevent overload.
An analog multimeter, or “needle meter,” as some people refer to it, is another option. Analog multimeters work great to test your guitar pickup’s resistance, but remember to always set them to zero before using them, or you will not obtain a correct measurement.

Testing Your Pickup Using a Screwdriver
In a pinch, you may use this simple method in addition to the easy method of testing a pickup, which is a multimeter. That won’t be as accurate, but it will show which of your pickups is the issue.
To identify which pickup is defective, just follow these simple steps:
- Connect your guitar to an amplifier.
- Maximize your volume and balance.
- Use a screwdriver to lightly tap each pickup.
- As the pickup is surrounded by an electromagnetic field, tapping it with a screwdriver while it is connected to an amplifier ought should produce a loud clicking sound. If one of the three pickups is silent, you have located the problematic pickup; if two or all three produce a loud noise, they are functioning properly.
- If your guitar’s pickup isn’t installed, you may connect a cable with a jack connection on one end straight from your amplifier to the pickup. If the pickup doesn’t produce a sound, try tapping it with a screwdriver.
What Causes a Faulty Guitar Pickup?
As you may know, the pickup is the electric guitar’s heart; no one will be able to hear those beautiful sounds you’re playing without that component. As was previously said, humbuckers and single coils are the two most popular types of guitar pickups.
Here are the common signs you need to know if you have a faulty guitar pickup.
- Brittle solder joints and degraded insulation
- Exposed to humidity, water, and moisture
- Exposed to a powerful magnet
- Incorrect installation
- Degraded insulation
Final Thoughts
You have it now! While preparing the lead wires for testing, just make sure your guitar is not connected to an amplifier. Also, never attempt to cut over any wires; always leave them intact .

FAQs
How do you use a multimeter to check the pickup polarity?
The multimeter’s probes should first be connected to the pickup leads after being set to ohms. Make that the meter’s red probe is connected to the positive pickup lead and the black probe is connected to the negative pickup lead. You ought to get a reading (this will vary from pickup to pickup)
What is a guitar pickup’s output voltage?
The usual output ranges from 100 to 300 millivolts.
What multimeter can measure?
Instruments called digital multimeters are used to measure things like voltage, current, and resistance. Digital displays make it possible for even novice users to interpret measured values quickly and simply
