Classic Acoustic Tone from Martin

The Martin 00-18 acoustic guitar delivers everything you could ask for in an acoustic for studio sessions — add your preferred electronics package, and it's an outstanding guitar for performance too. This Grand Concert model has a modified low-oval neck with a High Performance taper, a favorite among guitarists who prefer a thinner profile to bulkier necks. Spruce atop mahogany is a classic tonewood combination, offering a nice balance of powerful lows, vibrant mids, and detailed highs. An ebony fretboard and bridge, a real bone nut, and intricate detailing complete the package. If you've always wanted that classic Martin acoustic guitar tone, then you definitely need to try the Martin 00-18.

Timeless combination of mahogany and spruce

Classic Martin guitars throughout history have used spruce tops and solid mahogany backs and sides to create enchanting tone, and you'll find the same premium tonewood combination on the Martin 00-18. Chosen as much for its look as its tone, solid spruce has a wide tonal range with excellent projection. And because it's a solid-wood top, the tone of your 00-18 will age gracefully, with enhanced harmonics and greater tonal balance as the years go by.

Modified low-oval neck for smooth playability

Whether you need to survive long recording sessions or plan to play out late into the night, you'll be glad you got a Martin 00-18 acoustic guitar. The 00-18 features a modified low-oval neck profile with a High Performance taper. Its slim profile is easy on your hand, allowing you to play those extended sessions in comfort. The shorter 24.9" scale length makes complex chord voicings easier to reach. And the smooth-playing ebony fretboard is comfortable and finished to perfection. Guitarists at Sweetwater agree that the Martin 00-18 is perfectly suited for both fingerstyle and flatpicking.

Super-comfortable Grand Concert body style provides excellent tonal balance

Arguably one of the most comfortable body styles for acoustic guitars, the Martin 00-18 has a smaller than average Grand Concert shape. It's the perfect fit when you're looking for a more manageable instrument than larger body styles offer. It also means the 00-18 is a particularly good fit if you're a fingerstyle player.

Martin 00-18 Acoustic Guitar Features:

  • Acoustic guitar with premium Martin craftsmanship
  • Grand Concert body style has a smaller feel that's extremely popular for fingerpicking
  • Rich, timeless tone from the solid spruce top and mahogany back and sides
  • Select hardwood neck has a modified low-oval profile with a High Performance taper
  • Scalloped x-bracing enhances projection and tonal balance

Novice player review

I have been playing guitar for 10+ years but didn't get serious till I bought this guitar! I have owned countless guitars in the $ range. The moment I picked this guitar up and heard how beautiful it sounded, the price was no concern! I went to the local guitar center in sandiego and the sales men put me in the martin room and allowed me to play every martin on the wall ranging from $ and I played them all to the best of my ability for 2 hours. The moment I picked up the 00-18 it was all over, it was comfortable and sounded so amazingly beautiful! It was the perfect balance of highs and lows! It had just the volume I like and need. It was light and smelled beautiful! I was sold! I bought this guitar and it made me a better player because it ignited a fire in me to learn how to put its beauty to work!

00-18 with LR Baggs Anthem

When I told sales engineer Jeff Bohan I was looking into buying a new guitar I mentioned the 00-18. He told me it's one of his favorites. I couldn't find one in Pittsburgh to try out. So, I decided to take the plunge and order one without playing it first.

Jeff was very attentive to my questions and concerns. I've been in touch with him for several years now. Sweetwater is my "go to" source for instruments and music supplies/accessories. I'm a gigging musician and wanted electronics onboard the guitar.

Jeff recommended the LR Baggs Anthem. My son in NJ has one of those in his D-28, so I am familiar with it. I am aware that it sounds great. When Jeff told me about it and the installation option, I decided to go all the way. I bought the 00-18, LR Baggs Anthem, and Jeff walked me through a questionnaire to make sure the guitar came to me setup at the specifications I wanted. The set up is great! Action, comfort, and sound are all TOP NOTCH. I couldn't be happier with my decision to let Jeff guide me on this one.

For a self employed musician, this is a considerable investment/expense. I really wanted to try one out before buying, but I decided to take a leap. Glad I did.

Jeff Bohan is an outstanding person to deal with. Always helpful, professional, knowledgable, and friendly. He contributes to the reason Sweetwater sets the bar that the other companies strive to reach.

The luthier and set up technicians/inspectors at Sweetwater did an excellent job on the install and set up. I'm very happy with the whole process from top to bottom. The action on this thing is low and comfortable.

Last but not least, Martin guitars are just great. I like the small comfortable body of the 00-18. The simplicity of the design is what draws me to Martin guitars. They are absolute quality, but I really appreciate the minimalist approach to many of their models. The 00-18 is just how I like it. The plain fretboard dots, black binding, spruce top, ebony fretboard, and mahogany back and sides are simple and tasteful. The straight forward simplicity of it is what makes it beautiful to me. I dig the open style tuners too. It's cool to see the gears.

The tone is incredible and the projection is impressive for such a small bodied guitar. Feels and plays great. Very comfortable. I will enjoy this guitar for steady gigging and at home practice!

The case included is very nice quality. And, of course, I must mention the ever pleasing "new guitar smell".

Sweetwater has the pictures taken care of, but I did attach a few to show the nice install job they did for me with the LR Baggs.


Highly recommend Martin guitars and Sweetwater!

Thank you for all your help Jeff. I appreciate you.
Cheers from Pittsburgh, PA.

00-18 Martin Guitar

Great guitar! Sounds good, plays really well looks good I love this guitar!!
Music background: bluegrass, folk, traditional
Rated 5/5

Great for the studio

After seeing Bob Dylan playing one of these for years, I jumped on the Martin boat after years of Gretches. The neck is quite small in circumrance in guitar of this size but not a bad size. The sound amplifies well and is well rounded with a bit of twang for people who play country music akin to an electric telecaster tone. Highly recommended fo the professional.

Fantastic!!!

These 18's are amazing! I'm fortunate to have an excellent triple, double and single. I find this 00 to be the perfect balance for playing and vocal accompaniment. Sounds better everyday! Big thank you to my sales engineer, Shawn McCullough. Great guy, very knowledgeable and easy to speak with. I wouldn't have this guitar, if it wasn't for him. Thanks again Shawn
