Mixing Humbuckers and Single Coil Pickups – Should I Use 500k Ohm or 250k Ohm Pots?

Mixing Humbuchers and Single Coil Pickups

There’s plenty of discussion on the web about the correct value pots to use for single coil pickups or humbuckers, but very little information about mixing humbuckers and single coil pickups.

If you have a guitar that mixes humbuckers with single coils, you might be wondering if you’re using the best value pot. We are going to help answer that question and see what options are available to get the best tone possible from your guitar.

A Quick Overview of Potentiometer Value

The first thing we should clarify is what the value of your volume or tone pots have to do with the tone of your guitar.

Without getting too scientific, the volume and tone controls connect to ground, and a side effect of that is they create a path for your high-end frequencies to escape. Think of the value as a wall that your high-end frequencies need to jump over to escape. The higher the value, the higher the wall, and the harder it is for the high end to escape, which results in a brighter tone going to your amp.

Higher value pots make your guitar sound brighter. Lower value pots make your guitar sound darker.

Standard Values

Often, when guitarists talk about the values of their volume and tone pots, they are talking about a guitar such as a Fender Stratocaster or a Gibson Les Paul that has one or more of the same type of pickup in the guitar. There are countless models and brands of pickups, but electric guitar pickups are usually one of two kinds: single coil or humbucking.

Single Coil Pickups

The Fender Strat, Fender Telecaster, and countless other guitars use the single coil pickup, which is known for its in-your-face sound, bite, and clear notes. Single coil pickups are also known for piercing sharp tones that are brittle and harsh.

To combat the harsh tones of single coil pickups, we pair them with 250-k pots. The 250-k pots allow enough high-end frequencies to escape, it warms up the tone, and takes off some of the harsh edges.

Humbucker Pickups

The Gibson Les Paul, Gibson SG, and thousands of other guitars use humbucker pickups. Humbucker pickups are nothing more than two single coil pickups working together. The two coils are close to one another, creating a slight phase cancelation between them. This phase cancellation effect causes high-end frequencies to cancel out, producing a warmer tone than is produced by a single coil.

To prevent the loss of any further high end, we pair the humbucker pickups with 500-k pots. The 500-k pots do an excellent job of preserving what high end remains after the phase cancelation.

Combination Pickups

Guitars that use a combination of single coil and humbucker pickups are known as super Strats. Ibanez, Jackson, and many other guitar companies produce guitars with combination pickup schemes.

For the guitarist in search of the perfect tone, however, mixing humbuckers and single coil pickups can present a real problem. With such a combination, choosing to go with the 500-k pots can make your single coils sound harsh and brittle. Going with the 250-k pots can cause your humbuckers to sound dark and muddy.

Unfortunately, there is no perfect solution to mixing humbuckers and single coil pickups. There are quite a few steps you can take, however, that will help the situation and act as a workaround.

Pickup Selection

Fortunately for anyone mixing humbuckers and single coil pickups, there is no shortage of pickups designed to create any tonal characteristics. It’s not impossible, or even hard to find a single coil that sounds dark or a humbucker that sounds bright. The challenge is finding pickups that sound good together.

If you are using a 500-k pot and it’s making your single coil pickup sound harsh, replacing the pickup with something designed to create warmer tones is likely to leave you more satisfied than any other combination we can suggest.

The downside to this approach to mixing humbuckers and single coil pickups is that it can get expensive and tedious, but it’s a fantastic way to experiment with your tone.

Middle Ground Pot

If pickup shopping sounds expensive, there are still several options open to you, such as using a middle ground pot. Potentiometers are available in any value, and there are plenty besides 250-k and 500-k. Perhaps a 300-k, 350-k, or 400-k, will solve the problem and give you a nice even tone through each switch position.

The downside to this method of successfully mixing humbuckers and single coil pickups is that you’ll have to hunt down each pot value, most likely online. It can take a while waiting for shipping etc. and you may have several pots left over.

Two Volumes, One Tone

If your guitar has one volume and two tone controls, you can change it to have two volume controls and one tone. This way, you can give each type of pickup a volume control. The single coil can use a 250-k volume while the humbucker uses a 500-k. You can see what a circuit like that might look like in Figure 1.

The downside to this method is that it’s only viable if your guitar has one single coil and one humbucker. If there are any more than two pickups the wiring can get very complicated.

Bright Boost Mod

If you have more single coils than humbuckers, a bright boost modification may be the solution you seek. The bright boost mod uses a push-pull switch and a capacitor to brighten the tone.

If using this modification, you would install a 250-k standard volume pot and a 250-k push-pull tone pot. The 250-k pot would sound good when using the single coils but leave the humbucker sounding dark. When the push-pull is pulled out, it removes the volume and tone control from the circuit completely. Without a volume or tone control, the sound will get very bright.

The modification is easy to install and diagrammed in Figure 2.

The downside to the bright boost modification is that it will also affect your single coil pickups and can lead to accidental harsh tones if you switch to a single coil without pushing in the tone control. It’s also an extra step every time you want to use the humbucker.

Parallel Resistor Mod

If you have more humbuckers than single coils, the parallel resistor modification could be the perfect solution. The parallel resistor modification uses 500-k pots for humbuckers but uses a resistor to make the single coil see a 250-k load. This modification is quick and easy to complete, as you can see in Figure 3.

The downside to using the parallel resistor modification is that when you switch to middle positions that use the single coil with a humbucker, the sound will get very dark and muddy. As a result, your tone options are still limited.


There are a few more methods for mixing humbuckers and single coil pickups, and what you’ll find as you begin to experiment, is that your options are limited only by your imagination. The most important thing is to use your ears and listen to what they tell you. That said, finding pickups that work well with each other and the existing electronics will be worth the money and time. The other options can provide a band-aid and could even yield some unexpectedly great tones. You’ll never know until you start your testing.
