Guitar: Is a Roller Nut Worth It?

Roller nuts are a great addition to your guitar if you love to abuse your tremolo bar, but are tired of having to retune your guitar strings after extended tremolo use. But is it worth it to add this customization to your guitar?

Adding a roller nut is a big decision, and it’s very difficult to undo once added. It’s usually a kind of customization that alters your guitar’s neck permanently, so whether it’s worth it or not is up to your taste and how informed you are on what the change entails.

I’ll be going through everything there is to know about roller nuts in this article so that you can be as informed about it as possible and answer the question for yourself by the end.

What is a roller guitar nut?

A roller nut is a nut made up of camshafts and precision ball bearings. The main difference between this nut and a traditional nut is that the strings can roll on the nut without any friction. It’s meant to be an alternative to a Floyd Rose or a Locking Nut.

The lower friction is what makes it possible to use the tremolo/whammy bar without affecting the tuning of the string. The lack of friction also makes bending feel smoother, but it’s noted to feel strange at first.

What are the benefits of roller nuts?

The main benefit is that you can use the whammy bar with more convenience, but it’s important to note that unless you’re heavily using a tremolo, roller nuts arent’ going to be worth it for you.

Another benefit is that after they’re installed, roller nuts are less finicky to adjust and set up than Floyd Rose floating bridges and lock nuts are.

That’s about the only benefits that I could find to roller nuts. There is speculation that they have an effect on tonal quality and that being a benefit is dependent on your taste in guitar tone.

Why don’t all guitars have roller nuts?

Mostly, it seems it’s because they’re not the industry standard. Bone nuts are the most commonly produced nuts, they may not be frictionless like roller nuts, but they’re a single solid object.

This is the main drawback of a Roller nut. The moving parts wear down more over time and they need to be maintained regularly to stay functional.

Compare this to your standard bone nut that is self-lubricating and generally lasts ages without any maintenance and it’s easy to see why roller nuts aren’t more popular.

Another reason may be that guitar players are more used to the sound of alternative nuts. Aside from bone being used, more modern guitar nuts are made with “High Tech” plastics like TUSQ which is designed to mimic bone without the inconsistencies.

Are there specific use cases?

Well, aside from the tremolo effect. Roller nuts pair best with other hardware that improves the player’s convenience of using a whammy bar. While roller nuts allow frictionless movement of the strings, their primary use requires a bar for the bending.

Roller nuts are best paired with tremolo bridges as they work together to create the divebombs and harmonic squeals we love hearing so much. 

The main use is that the roller nuts keep the strings from going out of tune while playing, much the same way that a Floyd Rose bridge and neck do. 

Is installing a roller nut an easy upgrade?

Not really. The change is usually a permanent one and since the nut groove depth isn’t adjustable, if it’s too high or too low, you have to make changes to the neck’s wood itself.

This means that if you decide you don’t like the roller nut down the line, you may have some issues changing back.

As with any modifications you may want to make to your guitar. I always recommend talking to a guitar tech about it and it gets it done with them.

Is a roller nut really worth it?

It depends mostly on your playing style and how often you do divebombs and bends. The drawback of traditional nuts and the reason the roller nut was invented is that over time normal nuts tend to wear and can cause slipping or catching.

This means that repeated tremolo use and friction within the groove of your nut, may wear down and affect your string’s ability to smoothly slide between the groove, causing tuning issues.

A roller nut isn’t for everyone and it’s not a modification to take lightly. Some people love it and others hate it and you won’t be sure where you sit on it until you try it.

What’s great is that you don’t have to change your guitar to try out a roller nut if you’re simply curious about the feel. Guitar stores have guitars with roller nuts that you can play and test out any time you like.
