Guitar tone pot value is something most of us don’t think about unless you really like to get into the weeds of tone. But many players do like to mix and match them, optimizing their tone control and guitar to play, sound, and react just the way they want. So we’re going to take a look at the best guitar pots and caps, demonstrating how powerful mixing and matching them can be.

Mixed-pickup Guitars

If you’re playing a Strat or a Les Paul, worrying about your potentiometers and capacitors may seem unnecessary. After all, don’t you use 250K pots and .047 caps for single coils and 500K pots with .022 caps for humbuckers? Well, that’s definitely how many people do it. But what’s the correct pot value for an HSS Strat or Ibanez-style HSH setup? And what if you only have one volume and one tone knob to control it all?

If this is you, knowing how to mix and match pot values and capacitors starts to get important real quick. This article should help. But before reading on, remember, when it comes to tone, all things are subjective. The “best” practices are the ones that get you to the sound in your head.

Technical Definitions

Tone pot vs. volume pot

Volume and tone potentiometers are actually the same kind of pot. They are a variable resistor. Your volume pot sends the entire signal to ground, shutting it off . But a tone pot utilizes a capacitor that removes higher frequencies and allows specific frequencies to pass through unaffected.

Capacitor Values (Rating)

A pot’s rating is the resistance it places on your signal. It’s important to know that the lower the number, the more it restricts your tone’s frequencies.

Capacitor

A capacitor diverts the flow of specified guitar frequencies through your electronics. Depending on the cap value ratings affect different frequencies.

Guitar Tone Pot Value

Manufacturers rate every single guitar pot at a specific value. And generally, with higher-value pots, more frequencies are allowed to pass through the pot. This gives you a brighter signal with more top-end detail. The inverse is true with lower values. While this affects your tone as you roll the pot back, it also impacts your overall tone when you turn up to full volume.

The five most common pot ratings used for electric guitar are 25k, 100K, 250k, 500k, and 1Meg. Technically, each of these does work with any guitar pickups. But there are some general guidelines guitar builders follow.

• 25k or 100K pots: Active pickups
• 250k pots: Single coil pickups
• 500k pots: Humbucking pickups
• 1Meg pots: Jazzmasters, some Telecasters, and some active pickups

Keep in mind, these are not hard and fast rules. You can use a 500k pot with single-coil pickups. This will give them a brighter tone. You can also throw 250k pots on a set of humbuckers for a warmer tonality. But when you start combining different kinds of pickups, you’re forced to choose a rating that will satisfy both.

Mixing and matching

Most manufacturers use 500K pots for electric guitars with combo wiring schemes like HSS and HSH. This may seem to favor the humbucker tones, but if your single-coils are a bit bright, you can always roll back the tone knob. Passive guitar circuits won’t let you add more treble to a muddy humbucker, and a humbucker bridge pickup is also where many players spend most of their time on these guitars.

If you prefer sticking to the neck single-coil of your HSS Strat and only drop to the humbucker occasionally, 250k could be the way to go. This can give a humbucker with too much treble a warmer sound. And you can always get that treble response back with a brighter pickup. It’s all about experimenting and finding the best guitar pots and caps for your guitar and playing style.

Guitar Tone Capacitors

Guitar tone capacitors are what make your guitar’s tone knob a tone knob and not another volume control. And caps play by the same rules as potentiometers:

• Their ratings determine their performance.
• There are some accepted “standards.”
• It’s still totally up to you.

Adding a cap to a potentiometer turns the pot into a low-pass filter. The cap’s value determines how dark your guitar gets when your tone knob is all the way off. It also determines how quickly it gets there as your roll it back. It does this by sending selected high frequencies to your ground wires instead of to your output jack. That tiny electronic component is what tells your pot which frequencies to filter.

As a general rule, the higher the capacitor’s rating, the darker your tone knob will take you. There are three most commonly used ratings for tone pot wiring:

.015 µF

.015 µF capacitors offer fine control of your treble throughout the tone knob’s range, perfect for taming harsh frequencies without ever transitioning to a dark, muddy tone.

.022 µF

.022 µF caps are the perfect middle ground. They work great with both single-coils and humbucker and offer a balance of clarity and the ability to get warm and dark.

Tech Tips

Because of their versatility, we recommend starting with .022 µF when mixing and matching pots and caps. But ask yourself what you want from your tone knob and go from there.

.047 µF

Darker than the other two, .047 µF capacitors can be great fits for brighter guitars like Teles and Strats. But you’ll even find them in some jazz players’ humbucker-equipped guitars as they deliver the warmth and fat tone they need.

Guitar Tone Pot Wiring

HSS and HSH guitar tone pot is a bit more in-depth than other wiring schemes. This is especially true when you introduce push-pull pots and additional toggle switches to the mix. But they also offer unending ways to achieve treble bleed, split-coil, coil-tapped, series/parallel, and phase-switching options.

We have all of the wiring diagrams to help you get there.

For simplicity’s sake, we’re going to focus on our standard 5-way switch, Volume, Tone layout. You simply solder a lead wire between lug 1 of the volume pot and lug 3 of your tone pot in this wiring scheme. Then solder one lead of your capacitor to the center lug and the other to the top of the metal pot casing.

Tech Tips:

With this wiring, it’s best to think of the tone pot and capacitor as a complete circuit. It works in conjunction with the volume control to fine-tune your tone. It’s not an “in one side and out the other” affair.

Not only is this an easy way to wire a tone pot, but it makes auditioning other values and capacitors a piece of cake. If you don’t like the one you’re using, simply unsolder it, replace it with a couple of new solder connections, and you’re ready to go. If you’re handy with a soldering iron, this should only take a couple of minutes.

All of the numbers and ratings can be overwhelming when you first approach electric guitar pots and caps. But if you follow the basic guidelines above, we think you’ll find yourself modding your guitar in no time.
