Every experience guitarist knows the importance of their acoustic guitar strings. Different types of strings not only sound differently from one another but their durability is often quite different from model to model. And that’s not even mentioning the fact that different strings feel different and may impact how music is played. Strings which “feel” good to one guitarist may not feel right to another. Personal preference does have to be taken into account.

There’s plenty of things to consider when buying guitar strings, too. Not only does a guitarist have to take into account string composition, but they also have to consider string gauge and what kind of treatments have been applied to the strings to increase their durability. That’s why we’ve listed what we feel are the 10 best acoustic strings currently available. Although not every set is perfect for everyone, one of these sets will please even the pickiest of pickers.

Best Acoustic Guitar Strings Reviews:

10. Ernie Ball Aluminum Bronze

Manufactured with an enduring blend of aluminum and copper, these aluminum bronze strings tend to produce a sound that’s louder and clearer than traditional strings made of bronze. Made with steel hex cores, these strings are also capable of producing crisp high and stronger lows. However, unlike other types of strings, they have improved corrosion resistance that allows them to be played a lot longer before they need to be replaced. And they do it without the need of being coated. They’re available in a variety of gauges including extra light, light and medium gauges, so guitarists have a number of options available to them.

Acoustic Guitar Strings Buying Guide:

It doesn’t matter if you’re an experienced musician or if you just started playing acoustic guitar, there comes a time when you’re going to want to buy the best strings available. Before you can do that, however, you first have to take a few key features into consideration. Only then will you be able to find strings that fit your playing style. Below are a few key features to keep in mind when choosing acoustic guitar strings.

Guitar Type

As a general rule, acoustic guitars and classical guitars use different types of strings. Classical ones have nylon strings, and acoustic guitars have metal strings. And since they’re different, they aren’t interchangeable. Their tensions are different, so if you use the wrong type of strings, you can ultimately ruin your guitar. Another thing that separates classical strings and acoustic guitar strings is how they interface with the bridge. Nylon string guitars tend to tie off at the end, while metal strings will typically have strings with balls on the end.

String Gauge

As just about every guitarist knows, string gauge is a measure of the diameter of the string. Changing gauges can have a dramatic effect on how the music sounds, but it can also affect how the guitar feels when it’s played. Smaller gauge strings tend to be easier to play, but they aren’t as durable and tend to break easily. Higher gauge strings last longer, but they have a louder, heavier sound. So each guitarist has to measure the performance of the strings against durability and playability and choose the set that best suits them. Only then will they find a set that fits their playing style. Below are some of the more common gauges available:

Extra light: 0.010, 0.01, 0.023, 0.030, 0.039, 0.047

Custom light: 0.011, 0.015, 0.023, 0.032, 0.042, 0.052

Light: 0.012, 0.016, 0.025, 0.032, 0.042, 0.054

Medium: 0.013, 0.017, 0.026, 0.035, 0.045, 0.056

Heavy: 0.014, 0.018, 0.027, 0.039, 0.049, 0.059

String Composition

The composition of acoustic guitar strings vary from model to model, but they usually come in one of the 4-different types available. Below are the most common string compositions.

Bronze: These strings are made from a combination of 80% copper and 20% zinc. These strings are usually suitable for just about any type of guitar playing and can easily be recognized by their clear and bright notes. However, they tend to age fairly quickly due to bronze’s predisposition to premature oxidation.

Brass: These strings tend to age well, but they also tend to produce not only harsher notes than other strings, but they also deliver a very definitive metallic pitch.

Steel: Steel strings are known for their tendency to produce a softer and more laid back sound. They also aren’t as loud as other guitar strings and consider to be one of the easiest strings to play. Unfortunately, their ease-of-play comes at a cost because they tend to be less durable than other strings.

Phosphor Bronze: These strings produce bright sounds with just a touch of warmth. These strings tend to last longer than bronze strings and usually produce more of the typical “acoustic” sound when played that most people are accustomed to when they hear an acoustic guitar.

The Coating

Coated strings are available to just about anyone who wants them. When a string is coated, it resists dust, oil, metal, and dirt that the string may pick up while it’s being played. This ensures that it stays brighter longer and also helps prevent the strings from corroding prematurely. Unfortunately, many guitarists feel that there is also a drawback to using coated strings over non-coated strings. They feel that coated guitar strings have a reduced sustain and generally produce a lower output than their non-coated cousins. And this is true to an extent. Although the coating applied to the string protects it from the elements, it also limits how much it can vibrate. That’s how two of the same types of strings can sound so different from one another if one pair had been coated and the other one hadn’t been coated. It’s something that each guitarist is going to have to decide whether or not it makes a difference to them.

Although electric guitars generally have two different types of coated strings, Nickel Plated Steel NANO & Nickel Plated Steel POLY, acoustic guitars have three different types of coated strings.  Here are the three coatings generally available:

80/20 Bronze POLY

80/20 Bronze POLY

Phosphor Bronze NANO

What is the difference between these POLY and NANO coatings? NANO coatings tend to be lighter and more closely approximate the sound of uncoated strings. POLY coatings tend to be heavier, but they have a smoother feel and tend to be more durable.

How Often Should Acoustic Guitar Strings Be Changed?

Although there’s no general rule for how often acoustic strings should be changed, many guitarists change their strings twice a month. Of course, if the guitarist uses the guitar a lot, then they may need to change their strings more often. It might also be time to change them if they have lost some of their brightness or the strings are showing some corrosion. Wiping down the fingerboard and the strings with a dry cloth after every performance will slow the deterioration of the strings due to accumulated dirt, oil, and grime, but they’re still going to have to be changed on a regular basis to keep them sounding good.
