Best Strings for Martin D18 You Can Trust

The Martin D18 guitar is a dreadnought guitar, and we all know that dreadnoughts are quite on the big side, at least bigger than the standard C-shape acoustic guitars.

While this does not outrightly mean that some strings cannot work on it, some strings are just best with some kind of guitar.

I’m going to be listing some strings that you can trust for your Martin D18. I trust you will find this helpful.

5 Best Strings for Your Martin D18 You Can Trust

I know it will feel like I’m trying to sell you some bunch of guitar strings so I can make money off selling for the manufacturers (as an affiliate).

Yes, I wanna make money doing that (who doesn’t want to make money. LOL).

But you can trust the recommendations I give here, as I put in a lot of effort in deciding which guitar strings to recommend for your guitar.

The reviews of each of the recommended strings give you a good picture of what to expect from the guitar strings, both good and bad of the product, to help you make a good decision.

So, let’s get into it straight up — Best Strings for Your Martin D18

1. Elixir Acoustics String Phosphor Bronze with Nanoweb Coating

I’m not going to bother or bore you with the scientific details, but it’s important to let you know the wrap material used on this string is Phosphor Bronze.

This wrap wire was coated with Nanoweb. It’s what protects the strings against dirt, sweat and humidity. And it does this without sacrificing the quality of the tone produced.

If you are a sweaty player, this string will be a good fit as it’s not easily affected by sweat.

It does not also corrode easily and the tone also lasts long. Another quality to love about the string is the tuning stability of the strings.

It feels cool when you play the Elixir Phosphor Bronze Nanoweb Acoustic Strings, and the tone produced is rich and full, as is common among phosphor bronze strings.

Going for the light gauge should be a good choice, especially if you want a string that will be easy to play or you are a beginner.

Trying this string out for your Martin D18 is worth it.

It’s common knowledge that strings influence the tone produced by a guitar, even though factors like shape, size and kind of guitar can also affect the sound produced.


  • Full and rich sound
  • It last long
  • It maintains its brilliance well
  • Warm sound


  • It is not bright (Phosphor Bronze strings are not). If you want a bright tone, go for the 80/20 version.

2. D’Addario EJ17 Phosphor Bronze Acoustic Guitar Strings

Just as you can expect from any phosphor bronze, the tone produced by this EJ17 is warm, full and balanced.

We can probably say this string is one size that fits all music genres.

So, don’t be overly worried that you might be at a disadvantage if you choose a string good at a genre because you love to explore different genres.

And if you specifically just stick with one genre, it’s still a fit for you, as it’s good for all genres.

Also, you won’t have to worry about your strings corroding quickly.

Most of the time, the complaint from many guitar players is that their strings corrode and rust once exposed to sweat or humidity.

I’ve used a guitar string that corrodes on my guitar before, and I know how annoying the sound production can be. The corrosion dulls up the string tone.

But with EJ17, you won’t have to worry about all of that, as it is resistant to corrosion.

When you play with an EJ17, it sort of feels like you just got your guitar afresh because of the quality tone produced.

If you love bending, you should go straight for the lighter gauge.


  • Warm and full-tone
  • It feels great to play
  • Suitable for all genre


  • I’ll say preference will make the difference.

3. GHS Phosphor Bronze Acoustic Guitar Strings

Just as you may expect, since it’s a phosphor bronze acoustic guitar string, the tone produced by the GHS Phosphor Bronze Acoustic Guitar Strings is full, warm, rich and balanced.

This string is easy to play, and if you love to bend a lot while playing the guitar, go for the lighter gauges.

Just saying this randomly, I would not advise using a gauge that is on the heavy side for a small-sized guitar as they can’t withstand so much tension.

We all know that the Martin D18 guitar is kinda on the big side, so if you wanna use heavier gauges and you are experienced enough to use it, it’s nice.

If you are a beginner, just stick to the lighter gauges.

The GHS Phosphor Bronze Acoustic Guitar Strings are available in four ultra-light gauges: extra light, light and medium.

The strings can do a great job in any musical style you want them to. Give it some finger-style, strumming, blues and country, folks and bluegrass alternative, lead playing, rock and metal, shredding.

Just any musical style and the guitar string will do justice to the job.

Check out this short video of GHS Phosphor Bronze acoustic strings being played here.


  • Easy to play
  • Full, warm, balanced and rich tone
  • Easy to bend on the lighter gauges
  • Good for all musical styles


  • I’ll say preference will make the difference.

4. John Pearse Phosphor Bronze String

This string is the most balanced string you probably have heard.

The sound that comes from this string is round and warm.

It is pretty easy on the fingers. So, if you have soft fingers, this should be good for you.

Also, the tone comes with a lot of clarity, making it a good choice for any guitarist.

Another lovable thing about the strings is that they rarely break.

6. Dr. Strings Sunbeam – Phosphor Bronze Acoustic Guitar Strings

The usual notion and reputation that most phosphor bronze strings have is that they are warm in tone but not bright.

One thing that is unique about Dr. Strings Sunbeam Phosphor Bronze acoustic guitar strings is that it sounds brighter than most phosphor bronze strings.

It is not as bright as the 80/20 strings, but it is brighter than the usual phosphor bronze strings.

Another magic with the string is that it feels as though it sounds better with age. It keeps its tone production and brilliance well.

Also, Dr String Sunbeam is easier to play than other strings of the same gauge.

This translates to ease in bending this acoustic string.
