No-Load Pots – Why Use One?

No-load potsHere are a few reasons why you might want to convert your standard tone control into a no-load pot.

No-load pots look like standard Volume or Tone controls, and they function in similar ways, but they are commonly misunderstood components in the world of guitar electronics. For example, you can swap out your Tone control for a no-load pot, but it will not work for the Volume control. The benefit of using it as a replacement for your Tone control, however, is the resulting brighter guitar tone.

What Are No-Load Pots?

Traditional potentiometers move from one through ten in a linear path or with an audio taper. They will apply the most resistance to a circuit at the one position (full down), and the least resistance at the ten (full up).

The design of the no-load pot causes it to remove itself from the circuit altogether when the volume reaches ten, by using a built-in off switch. The potentiometer will function as usual from one to nine, but shut off once it reaches ten and will no longer apply any resistance to the circuit.

Why Use a No-Load Pot?

Typically, both your Tone and Volume controls connect to Ground. These connections will cause some of your high-end frequencies to leak to Ground, which will result in a warmer tone from your guitar.

The manufacturer of the guitar chooses the values of our Volume and Tone controls based on the type of pickups we are using. If we are using single-coils that are often very bright and sometimes harsh and brittle sounding, we use 250k pots. 250k pots allow a lot of high-end to escape to Ground and it warms up the tone, making single-coil pickups more useful and musical.

Humbucker pickups are naturally warmer sounding, and using 250k pots could result in a very dark and muddy tone. For that reason, humbuckers use 500k potentiometers, which allow less high-end to escape and sound brighter. No matter what value you use, standard pots are always slightly ON and therefore will continuously leak some high-end frequencies to Ground.

No-load pots can be 250k or 500k, and they will operate as usual from one to nine, but they will shut off at ten. When they shut off, the connection to Ground is severed, and no high-end frequencies can escape to Ground. This configuration leads to the brightest possible guitar tone.

When Would I Use A No-Load Pot?

There are a few reasons why you might want to convert your standard tone control into a no-load tone control.

Your Natural Tone is Too Dark

Maybe you bought the guitar that way, or you purchased pickups you thought would sound different and your guitar sounds very dark and muddy.

You Are A Tone Purist

If you are someone who hates to have your guitar signal run through any extra circuitry, you might be interested in performing this modification. When the no-load pot is at ten, your signal travels a shorter path through fewer wires.

You Never Touch Your Tone Control

If you always leave your tone control all the way up, this modification can give you a brighter tone and more tone options without any sacrifice. If the resulting sound is too bright, you can turn the control to nine for the sound you’ve always had.

High End Lost Elsewhere

Any time you have a lot of devices in a signal chain or use long cables, the high-end is always something that suffers. This modification can be a real help by injecting high-end frequencies that otherwise wouldn’t be available to your signal.

Summary

We recommend this modification because it is not too challenging to complete. We modify a part of the guitar that many people neglect. The mod is entirely reversible, and it can enhance your tone as well as make it better suited for large pedalboards and cable runs.

You can achieve the same tone you had before, by turning the control to nine, so there is no real downside to using no-load pots.

  1. Excellent write up. A lot of people don’t get this and this explains it very well. I’m big on eliminating the tone control all together on most of my guitars and you get a wicked difference from the pickup for sure. Nice job!!
