The Martin D-18 has a simple design and a heart-touching tone. The price of this acoustic gem ranges from $2,500 to $3,400, depending on the modification.

In this review, I am going to have a look at the Natural dreadnought design, which is also the most affordable.

After scrutinizing its sound, playability, and build quality, I shall compare it to one of its most viable alternatives – the Martin D28. 

Let’s check it out.


The Martin D-18 Natural showcases a vintage dreadnought design coupled with rich and full tonality. Although this is an acoustic guitar, electronics can be attached optionally. The 25.4″ scale and 14-fret body size make this instrument a bit challenging for smaller-framed players.

The dovetail neck joint is present on D-18, along with a forward shifted X-bracing pattern. The solid Sitka spruce top and the mahogany back and sides guarantee that this guitar’s tone will only get more profound and mature over the years. On the whole, Martin D-18 is made to last a lifetime.

How It Sounds

Without exaggeration, the Martin D-18 is one of the best-sounding acoustic guitar in the world. It is as loud as a full dreadnought is expected to be, yet it’s capable of astounding harmonic complexity. 

The superb mid-range pump is well-complemented by a balanced bottom end. The forward scalloped bracing delivers an excellent bass with a projection that could last for as long as you need it. All of these characteristics make D-18 very suitable for band playing.

This is a big guitar with a peculiar character. It promptly responds to different levels of attack without losing its even tone. Martin D-18 lends itself accurately to a wide variety of music styles. 

However, its 14-fret size can be a challenge for smaller-framed fingerpickers. On the subject of versatility, I must say that Martin D-18 can go all the way from a loud boom to a soft whisper.

Build Quality

The build quality is what makes all Martin dreadnaughts yardsticks in their own right. Previous D-18 modifications feature the standard scalloped X bracing, whereas the MD18 Natural boasts a revolutionary forward-shifted X scalloping. The tortoiseshell binding matches the pickguard and adds a classy finish to the guitar’s overall look. 

The vintage-looking enclosed tuners have been replaced by nickel ones with butterbean knobs. The neck is made of a single piece of mahogany and connects to the body with a dovetail joint, exemplifying a superior craftsmanship level.

What Others Are Saying

Fingerpickers from around the world are unable to find adjectives strong enough to describe this pearl in Martin’s acoustic collection. 

One enthusiast writes that since the moment he got his D-18, he’s had a hard time putting it down. That’s how playable the thing is. Another guy gives far more practical advice about stringing: a phosphor bronze set of 12″s will show the full potential of your Martin D-18. 


Pros and Cons


  • Many parts of the Martin D-18 are handmade
  • Solid mahogany back and sides
  • Solid Sitka spruce top
  • Innovative forward-shifted X scalloping


  • Some guitarists find the neck of the Martin 000-15M more comfortable

Martin D-18 vs D-28

 Here are the differences between these two models that primarily affect their tone.


The D28’s back and sides are made of rosewood, whilst that of D-18 are all mahogany. Mahogany’s porous structure accounts for D18’s warm sound. As Rosewood is harder, D28’s sound is more articulate.

Compared to D28’s standard X brazing, the scalloped forward-shifting bracing of D-18 increases the bass response.


Martin D-28’s Grover tuners convey an air of modernity, while D-18’s tuners are old-style open-gear ones.


With a retail price starting from $3,000, Martin D-28 is a notch pricier than D-18.

Martin D-18 is an excellent acoustic guitar for experienced fingerpickers. Being a full-sized dreadnought, it is loud enough for most clubs. However, if you are up to some big-hall performances, perhaps you should buy a D-18E – the electronic acoustic version.

D-18’s design has been evolving since the mid-1850s. Today, its signature feature is the forward-shifted scalloping of the brace.
