A High Set of Standards

The new Standard 00-18 is made in the 00 “Grand Concert” size, in Martin’s Standard Style 18, which includes traditional South American mahogany back and sides and a Sitka spruce top. It is the first 14-fret 00 in the Standard Series of professional-level guitars, and features the same level of excellent construction and materials that make its larger siblings so successful and popular. Like the Standard D-18 and 000-18, it has the same all-solid wood construction, same ebony fingerboard and bridge, the same full gloss nitrocellulose finish, and the same traditional, hand-fit dovetail neck joint used at C. F. Martin & Co. since its founding in 1833, which provides optimum transfer of tone-producing energy from the neck to the body for the signature full bass, midrange presence, and violin-like purity to the trebles that define classic Martin tone.

But as a 14-fret Grand Concert-size 00, many may expect a trade-off between having a smaller physical body for the sake of comfort and portability and a significant drop in the amount of “body” in terms of the sound it puts out.

Well I can tell you, a lot of people are in for a very big surprise when they pick up this little guitar that sounds anything but small. It provides a thoroughly satisfying playing experience, with an uncompromising strength of character at the heart of its remarkably robust voice.

A Welcome Return

Martin 00-18 full sizeThe last time the Martin 00-18 was made in any significant numbers it had straight, non-scalloped bracing, a rosewood fingerboard and bridge, and a skinny 1-11/16” neck. The high watermark for 00-18 production was 1954, when 800 were built.

Relatively affordable for grassroots musicians, the 00-18 played a part in the Great Folk Boom of the late ‘50s and early ‘60s, and served as a comfortable “writing sofa” guitar for professionals like Johnny Cash and Bob Dylan. But after Woodstock came and went, the model all but vanished from the scene, even if it remained the favorite recording acoustic guitar for Steve Howe of Yes.

After the turn of the century, 00-18V entered the now defunct Vintage Series in 2003. Made with scalloped 1/4” bracing and pre-war Style 18 appointments, including the ebony bridge and board, and a 1-3/4” modified V neck, it was a feisty bantam-weight acoustic, offering a punch and roar much bigger than the typical Grand Concert size guitar.

Some people bemoaned the removal of the 00-18V from the Martin line, because it sounded so good, if even if they didn’t actually buy one. But there were many others who bemoaned the fact it had a V neck, and didn’t buy one for just that reason.

Well, this new 00-18 is basically the 00-18V, with its pointy V neck replaced by Martin’s modern High Performance neck, combing the Modified Low Oval profile with the sleek High Performance taper, which starts out at 1-3/4” at the nut, but is only 2-1/8” at the 12th fret. In essence, it is the Standard 000-18 in the slightly smaller 00 size.

A More Perfect Union?

The 00-18 and 000-18 have a short-scale neck that allows for those great bluesy string bends, fully two-frets worth with light gauge strings. But the slightly smaller body of the 00-18 brings the fretting hand a little closer to the player’s body, making everything that much more comfortable and easy to play.

The 00-18 and 000-18 each have a flexible Sitka spruce top, made all the more responsive by scalloped 1/4” Sitka spruce bracing, just like that used on the long-scale Orchestra Models of the Vintage Series and Standard Series. So, the 000-18 is basically a short-scale version of an OM-18, since the OM and 14-fret 000 have the exact same body.

In fact, the Grand Concert soundboard of the 00-18 may be a more-ideal size for the specific string tension that comes with a short-scale neck, when it is brought to bear upon a top with scalloped 1/4” Sitka bracing.

One thing is certain; the 00-18 puts out a full-bodied voice. It is responsive enough to accommodate nuanced playing as well or better than most other world-class fingerstyle guitars. Expressive and glowing tone blossoms with the slightest touch. But it also has the support needed to withstand a flatpick with some muscle behind it, or when a player digs in with their fingers to mine some weighty Sitka tone enriched with the gleaming, woody sonic qualities of genuine South American mahogany.

Although it is true the 000 has a rounder, more pronounced low E string, the bottom bass note from the 00-18 prototype I played never got lost in any kind of playing. It retained a honed but strong definition in its tonal signature. So, I might say the 00-18 is more like a strong safety than a linebacker, not as hefty, but having an impressive punch and power for its size.

It will never have the massive bass of the D-18, and dread players may prefer the 000-18 as a result. But the bottom E string of the 00-18 never gets lost when it comes to the fundamentals, and it has an undertone welling up from the deep end that permeates through the mids and treble, like the best mahogany Martins always do.

My Hogany Has a Sitka Top

I have enjoyed mahogany guitars with every type of top wood out there. But I am especially enamored of guitars made of Big Leaf mahogany and Sitka spruce, which provides my ear with that Goldilocks’ “just right” combination of muscle, clarity, and tonal coloring. And this 00-18 prototype was so very gratifying in this regard.

The original “mahogany” (Swietenia mahogani) came from the islands of the Caribbean, and was all but cut to extinction by the time C.F. Martin Sr. set up shop in New York City in 1833, before moving to Nazareth, Pennsylvania. So his guitarmaking decedents turned to the species known as Big Leaf mahogany (Swietenia macrophylla) from Central and South America, when looking for a more-affordable alternative to South American rosewood. The first Style 18 guitars made in mahogany were built in 1917.

Guitar players quickly came to appreciate mahogany’s unique tonal properties. Compared to the denser rosewood sound, it has an open and airy quality, with a sunnier disposition ringing with chiming clarity. It has less complexity to its harmonic overtones and resonating undertone, but it still has plenty of both.

While mahogany is said to be brighter than rosewood in terms of the overall voice, Big Leaf mahogany has a greater bass response than other members of the mahogany family. It has warm woody depths without being overly murky, so it allows the fundamental to ring strong and clear with distinct definition that “cuts” when played alongside other instruments.

Sitka spruce adds some color and warmth to that clear, clean mahogany sound. It accentuates the warmer shadows in the mahogany tonal landscape, while giving the fundamental notes some lean muscle, particularly in the unwound treble strings. And overall, it provides a palatable increased richness to that ethereal presence rising from the body of a well-made mahogany guitar.

And just as a lighter, more-refined scotch malt whisky is most influenced by the cask that ages it, compared to the heartier and heavier malts, so too does a mahogany guitar take on and show off greater tonal influence from the species of wood used for the soundboard, compared to the denser and more tonally complex rosewoods.

Adirondack spruce provides a bell-like chime of crystal clarity, but it is a drier and snappier sound overall, and rather arid and straight forward in its effect, when paired with the less-complex harmonic structure of mahogany tone. European spruce offers a more metallic ring in its own bell-like chime, as well as some Sitka-like richness, but it is so awash with a diffuse sonic aura that is more of a cream sauce emulsion, while Sitka remains leaner but still beefy.

While Sitka does not have quite the headroom of Adirondack, with the tone spreading out under a hard attack rather than condensing and popping, as heard in Adirondack’s bark, it still holds up very well under normal playing conditions. The classic Bluegrass canons from the 1950s are fine examples of that. As too are the 00-18s favored by hard-playing Blues masters.

I play pretty hard myself. But I also like to ease off the throttle at times and let the guitar lead me to “the zone,” where the resulting tone of Sitka over mahogany can be quite luscious indeed. And that is exactly what happened when I laid back and eased into the new 00-18. It provides a relaxing and comfortable playing experience that rewards the guitarist with a prosperous voice, lavish with so much classic Martin presence in the undertone resonance and the wafting high harmonics.

Modern Martin Legacy

When I sat down to discuss the Summer NAMM Martins with Tim Teel, Director of Instrument Design, and Fred Greene, VP of Domestic Manufacturing, the conversation began with Martin’s renewed commitment to making the Standard Series the place where the world’s best professional guitarists and discerning amateurs alike can reach for their next guitar. And it turned to Martin’s methods of getting a sense of balance across their entire product line, while weeding out poorer sellers to make room for new models.

Fred Greene said to me, “Of course there will always be some models that won’t provide dazzling sales numbers, but need to remain in the catalog because of their historical significance. Like the 00-18 for example; we need to have a 14-fret 00 for legacy reasons.”

I believe Martin may be surprised how well this new 00 sells. Just putting it in the Standard Series and giving it the same neck as the 000-18 provides a bit more affordable price point than the 00-18V managed. And the High Performance neck makes it directly competitive with the majority of acoustic guitars on the market. Personally, I find the short-scale version of the modern Martin neck to be the most comfortable.

For those wanting the big V neck experience on a versatile mahogany blues machine, the CEO-7 would be my recommendation. But I expect the new 00-18 to ultimately outsell the 00-18V, and probably the CEO-7 in time.

In this monumental Year of the Dreadnought, perhaps the most surprising success story in the entire lineup of 2016 Martin guitars is this unassuming but untimorous 00-18.

Many people will find the new 00 ideal as a living room sofa guitar, because of how comfy it is in the lap and how effortless the short-scale neck is to play. Others will find it to be a very good travel and touring guitar that does not compromise when it comes to tone. And yet others will find it a wonderful smaller companion for their larger dreadnought or jumbo.

It is an absolutely successful design and a worthy addition to the Standard Series and Martin’s perpetual legacy.

And that is one man’s word on…

  1. Spoon,

    I am commenting on this nearly three year old review to remind you and your audience of the value of your archival reviews. As I mature as a guitarist, my needs and interests are evolving from my dread-only origins. I have only recently discovered the wonders of short scale on smaller bodied guitars which has led me to a beautiful but lonely custom shop 00-18 that has been gathering dust in my dealer’s warehouse for a couple of years. I have a feeling it will find a home soon. This review is certainly helpful.

    The detail of these reviews is without equal. I was especially edified by your tangent into the effect of various spruces over mahogany. Timeless information! And, I always listen to the videos through headphones at high volume with my eyes closed. The sound you generate is incredible. Thanks for doing what you do.


    1. Well thank you, Indy, for your comments.

      The 00-18 is indeed a very successful model, as is the 00-28.

      Over the past year or so I was beset with various obstacles when it came to having the time and ability to maintain my writing pace. And I know the older reviews could use my own re-reviewing, in case any specs have changed on models still available for sale.

      But right now I am trying to carve out the time to review the NEW Martins for 2019. I am already working on them, but I must devote more time to the writing that actually brings me fees. I am mindful, however, of the generous donations this site brings in from time to time, which helps keep it afloat. And I am happy to honor the obligation I feel to keep the reviews coming.

      And more are on the way!

      Thanks again for your acknowledgement of the words and videos I put together to provide one man’s take on this worthy musical instruments.

      Would that I had the time and proximity to do the same with many other brands and builders. Alas, every time a local NYC dealer has shown interest in allowing me access to their shop and stock to make such videos as these, their corporate overloads refuse to support the endeavor. But hope springs eternal!

  2. Hello Spoon,
    I have listened to your video on Youtube for both 00-18 and 00-28(2018) for hundreds of times. They both sound great! But that’s also the problem for me since I am choosing between these two and couldn’t decide. I’m wondering which one would you recommend? Most of the time I sing along with guitar by both strumming and finger picking.

    1. I know just how you feel.

      Entirely my own matter of opinion is that rosewood is better for solo artists accompanying their own singing, especially if they do not have a deep round voice. On the other hand, mahogany records much more easily because it does not have the warm, thick blanket of undertone in the low-mids that helps give rosewood its meatier sound.

      But honestly, I go back and forth between the two as to which I would prefer if I could have only one, no matter what body size is under consideration.

      1. Thanks Spoon,
        I just ordered a 2018 version 00-28. It’s my first Martin and I can’t wait until July to receive it!
        Thanks for all the Youtube videos that you have made. I have been watching and listening over and over again. And also the most in-depth review on the guitars in your blog. It’s the best and most detailed review that I have read. : )

  3. Hi Spoon,

    Does the 00-18 have forward shifted bracing? Whatever the bracing, what are your thoughts on how the bracing suits the body size?

    Thank you.

    1. No, it does not have forward-shifted bracing. The 14-fret 0, 00, and 000 sizes never had the X braced moved back to the pre-1938 location, relative to the bridge plate.

      As for the bracing suiting the body, I feel it is ideal! I advocated for Martin to put 1/4″ OM-style bracing on their 000s for decades. They finally did with the 000-18. But I think that bracing with a Sitka spruce top is even better on the 00 top size. Both the 00-18 and 00-28 are just so alive and responsive, they practically glow with radiation when the attack on the strings has the soundboard vibrating “in the zone” of optimum resonance.

      1. Thank you Spoon. I happened upon a 0-18 recently and was amazed at the volume of sound and the richness of the tone coming out of it. It sounded a lot like your demo of the 00-18. Those are some wonderful small body guitars Martin is turning out now. And a thank you for this blog as well as your contributions on the UMGF. 🙂

        1. Well thank YOU, John, for the kind words and reading the blog. The 0 has a bit less bass and volume than the 00, but not by much!

  4. Hoping my comment can still be read even if this is an old review. If you could only have one guitar total and you had to choose between the 000-18 and the 00-18, which one would you choose? I’m in this current situation, and your input and opinion would help me immensely. Thank you for a great review.

    1. You are welcome Fil. Thanks for the comment!

      Well, I have two 00s and two OMs, so for me the easy answer is the 00-18. But if you are asking about a comparison, it depends on the player. The 000 has a noticeably bigger bottom bass string, which some people do not feel is big enough. Those people would likely prefer the GP or D body size, or even the OM since the longer scale does provide a slightly larger voice overall compared to the short-scale guitars.

      But, the 00-18 and 00-28 are both very successful guitars. And I have to say, when it comes to Sitka spruce tops with Sitka spruce 1/4″ scalloped bracing, I think the 00 top size is perfect for that bracing. They just sound SO GOOD when one is playing at the right attack to get the top moving with the optimal vibration and resulting resonance. And that sweet spot is very easy to find.

      But there is still something to be said for having a little more bass throb, which the 000 provides.

We and our readers would very much like to hear what YOU think.
