Whether you're in possession of a brand new beginner acoustic guitar, a money-is-no-object dream guitar, or a treasured old friend that needs some love, your acoustic guitar will be pretty useless without a set of the best acoustic guitar strings. There's really no feeling like restringing your pride and joy and getting to play your favorite songs and licks on a fresh set.

Whatever type of guitar you have, – whether it's an acoustic guitar, electric guitar, bass guitar or even a ukulele – it's important your instrument is fitted with the right strings to suit your needs and playing style. If they're too thick you might find the instrument difficult to play. Too thin and they might snap right when you're playing a crucial bend. Whatever the situation, making the right choice of strings is an important decision.

This expert guide outlines some of the best acoustic guitar strings on the market to help you get to the right set, fast. Follow our advice and you can get on with the business of playing.

Best acoustic guitar strings: Guitar World's choice

When it comes to buying the best acoustic guitar strings for you, it's important to consider how they're going to be used. Strings for strummers – both in thickness and durability – are quite different from strings for pickers. You should be changing your strings regularly anyway – once a month is a good rule of thumb if your budget allows – so if you don't like one set you don't have long to wait until you're onto the next set.

That said, if you're looking for a solid all-round set of strings as a quality starting point, the Ernie Ball Aluminium Bronze sets are hard to beat. With the clarity and projection of an uncoated set, and the longevity of coated strings, these will fit the bill for most applications and most players.

1. Ernie Ball Aluminum Bronze Acoustic Guitar Strings

The best all-rounder acoustic guitar strings

Price: From $9.99/£11.49 | Spec: Steel core, aluminum bronze winding, uncoated

Premium protection
For all types of player
Bright sound
Can be too bright sounding at times

Strings take quite a beating over the course of their lifespans. Whether it’s changes in temperature and humidity, or simply in being constantly tickled by your sweaty fingers, the life of a string is a tough one. Hence why string manufacturers offer 'coated' strings, which reduce the effects of corrosion. Coated strings, however, don't appeal to everyone.

The Ernie Ball Aluminum Bronze acoustic guitar strings bridge this gap by using aluminum oxide wrapping, rather than coating, to offer protection without compromising on projection. They create a wonderfully bright sound, perfect for fingerpickers and strummers alike.

2. D'Addario Nickel Bronze Acoustic Guitar Strings

The best acoustic guitar strings for full-band situations

Price: From $11.99/£9.99 | Spec: High carbon steel core, nickel-plated phosphor bronze winding, uncoated.

Lets your guitar's tone breathe
Great for full band setups
Not as durable as coated

The D'Addario Nickel Bronze set might be right up your street if coated strings just aren't doing it for you.

Uncoated strings offer the ultimate in clarity and crispness, meaning your guitar will sing in the way the manufacturer intended. The tradeoff is that they may not last as long. However, acoustic guitar strings generally come at a modest price, so if uncoated strings feel right for you, they're definitely worth the extra regular investment. 

These strings feature nickel-plated phosphor bronze, wrapped around a steel core. Nickel bronze strings are more commonly used for electric guitar strings, but they do a superb job of accentuating the mid-range frequencies of an acoustic guitar. This makes them perfect for full-band situations where the guitar needs to sit nicely in the mix as a whole.

3. Martin 'Clapton's Choice' Acoustic Strings

First choice acoustic strings from one of the best in the business

Price: From $7/£7.99 | Spec: Steel core, phosphor bronze winding, uncoated

Consistent from pack to pack
Phosphor bronze can lack that 'zing'

Eric Clapton inevitably springs to mind when you think of the best guitar players of all time. While for most players earning a signature guitar would be an achievement, Eric has reached that special status where he actually has a set of signature strings bearing his name.

The Martin Clapton's Choice acoustic guitar strings are phosphor bronze in their make-up, and are impressive in their consistency. Whereas 'bright' strings can sound dead and dull after a while, these maintain a steady level of clarity for longer than expected. If they're good enough for Clapton, they're probably good enough for you, too.

4. Fender Dura-tone Acoustic Guitar Strings

These coated strings balance tone with longevity

Price: From $10/£8.49 | Spec: Steel core, phosphor bronze winding, Dura-tone coated

Unrivaled durability
Range of gauges available
Reasonably priced
Coating changes the feel

Despite the tonal benefits of using uncoated strings, there are situations where using coated strings may be prudent. Changes in humidity can have a huge impact on string life, tuning stability and tone. Additionally, if the guitar is being used by different players, the strings' lives can be shortened.

By coating the strings in their patented 'Dura-tone' micro-treatment, Fender claims they can last up to five times longer than regular, untreated strings. These coated strings could be a worthwhile investment if you're a sweaty player, or just hate changing your strings.

In this range, Fender offers a cheaper 80/20 Bronze string, and a more expensive Phosphor Bronze string, both with Dura-tone coating.

5. Ernie Ball Earthwood Phosphor Bronze

The guitar strings favored by the big names of acoustic guitar

Price: From $7/£7.99 | Spec: Brass-plated steel core, phosphor bronze winding, uncoated

The pro's choice
Warmth and clarity
Pleasing treble and bass
Not too expensive, but not the cheapest, either

Another entry from the king of strings now. The Ernie Ball Earthwood series is carving itself a nice niche through offering the warmth and clarity you'd expect from a set of phosphor bronze strings. They have a more balanced tone than you might expect, with treble and bass frequencies nicely tuned with one another - perfect for solo performances (or just about anything else you can think of).

The list of professionals who use these strings is indicative of their capability; John Mayer, Paul McCartney and Brad Paisley all swear by Earthwoods, which gives you confidence they'll be great for mere mortals too.

6. Elixir 80/20 Bronze with Nanoweb

These acoustic strings use nano-tech for long-lasting performance

Price: From $13/£13 | Spec: Steel core, 80/20 bronze winding, Nanoweb coated

Protection without impacting tone
Highly playable
This level of protection costs

Continuing with coated strings, we have the Elixir 80/20 Bronze with Nanoweb. Elixir knows a thing or two about coating strings, and has developed a patented coating which the company claims offers the same protection as regular polymer coatings, but without the tonal drawbacks.

In our experience, this is certainly true. These strings last longer than uncoated strings do, yet at no point will make you feel like you're compromising tone in order to achieve this durability. A noticeable reduction in the dreaded 'finger squeak' was also noticed, making these a highly playable, great sounding string.

7. Martin Authentic Acoustic Superior Performance

A tried and tested classic from one of the best names in acoustic guitar

Price: From $6.49/£5.99 | Spec: tin-plated steel core, 80/20 bronze winding

Huge choice available
Ace tuning stability
Corrosion resistance
Not much

Just as you wouldn’t hang a Picasso in a chipboard frame, Martin’s Authentic Acoustic string series is worthy of the luthier’s hallowed instruments. There’s a choice of flavors, from the Retro pack with its Monel wrap wire to Tommy Emmanuel’s custom gauges. 

But a solid first stop is the Superior Performance set, available in 80/20 bronze or phosphor bronze, and featuring highest tensile-strength core wire, tin-plated on all six strings to beat corrosion.

8. Gibson Masterbuilt Premium Acoustic Strings

Meet Gibson’s best acoustic guitar strings

Price: From $7£7 | Spec: Steel core, phosphor bronze winding, uncoated

Produces a bright tone
Thicker than some strings

When the company produces acoustic guitars as legendary as the J-45 and Hummingbird, it's only right that Gibson also has a range of strings that live up to reputation. The Gibson Masterbuilt Premiums do just that.

Continuing the phosphor bronze theme, these strings do run slightly thicker than equivalents from other brands. But the tone you get matches clarity and purity of tone with longevity, to create a potent package for any player.

These strings are also available in an 80/20 bronze version, if you want to pull a little more high-end brightness from your acoustic guitar.

9. Dean Markley Blue Steel Acoustic Guitar Strings

The best acoustic guitar strings with an unusual twist

Price: From $7.99/£7 | Spec: Mandolin-wire hex-core, Nickel plated steel outer wrap, uncoated

Innovative coating
Sound great
A bit gimmicky?

We're all for a bit of innovation here at Guitar World, hence why we were naturally drawn towards including the Dean Markley Blue Steel strings in this round-up. 

The Blue Steel range is unique in that the strings are cryogenically frozen using liquid nitrogen to -320 degrees prior to packaging. This, the manufacturer states, tightens the molecules and minimizes the microscopic gaps into which gunk and sweat can hide.

The jury's still out on whether the science yields noticeable results on this one, however these strings sound great and in our tests lasted noticeably longer than regular uncoated strings.

Best acoustic guitar strings: D'Addario XT strings

10. D'Addario XT Acoustic Guitar Strings

A great option for strength and tuning stability

Price: From $14.99/£13 | Spec: phosphor bronze and 80/20 bronze options

Supremely effective coating
Options to suit all styles
Great tuning stability
Coating isn't for everyone

D'Addario is a company known for its dedication to innovation in guitar strings, and the XT line-up boasts its most advanced yet.

These meticulously designed strings combine all of D'Addario's bright ideas - including high-carbon NY Steel, fusion twist technology and, of course, those irresistible colored ball ends - and adds a new string coating that not only triples the lifespan of the string but feels identical to uncoated strings.

They're available in steel- and nylon-string offerings, both of which offer up to 42% stronger construction and 131% better tuning stability than regular strings.

Best acoustic guitar strings: DR Strings Dragon Skin

11. DR Strings Dragon Skin Acoustic Guitar Strings

The best acoustic guitar strings for sweaty palms

Price: From $9.99/£10 | Spec: Steel core, phosphor bronze winding, K3 coated

Won't corrode
You can sweat away!
Not the cheapest

We couldn't miss out an option for the sweatier palmed among us. The DR Strings Dragon Skin sets feature a unique coating which the firm says is both ultra-hard, and doesn't dampen vibration. DR believes softer coatings can dampen your tone, or add in unwanted overtones, which is exactly the opposite of what you want to happen. 

The result is a range of strings which are almost impervious to corrosion, yet retain clarity and articulation.

Best acoustic guitar strings: Buying advice

If you're at an early stage in your guitar playing career, you might be confused why there are so many different variables when it comes to the best acoustic guitar strings. Different thicknesses, materials, coatings and prices all make for a bit of a minefield if you don't know what you're looking for. Allow us to help...

Acoustic string material

Typically, string material is the first thing you'll want to pay attention to. This will be one of two things, steel or nylon, and this is a key characteristic of the guitar itself.

You can't put nylon strings on a steel-strung guitar, and vice versa. Within the steel niche are more subsets to choose from, each with their own properties, benefits and drawbacks. These include wrapping a steel core with aluminum, copper, bronze or nickel.

String thickness

Then, you'll find strings come in varying thicknesses, known as the string's 'gauge'. Thinner strings are favored by fingerpickers and sound brighter, but are more prone to snapping.

Thicker strings, favored by strummers, produce a more pronounced low-end, and tend to last longer but can be challenging to play if you're not used to them. If you're someone that plays a bit of everything, naturally we'd recommend opting for a gauge that sits somewhere in-between.


Finally, the coating of the strings is important. Amongst the choices in this guide, you'll see strings coated in various materials which reduce corrosion from sweat and other gunk. While these strings will certainly last longer, the tradeoff is that there may be a dip in the resonance and sustain of the tone. Coated strings will undoubtedly cost a bit more too, as the manufacturing process is more complex. 

Ultimately it'll take a bit of trial and error to find the set or variety which is right for you, but once you find the right acoustic guitar strings for you, you'll be set for life.
