A Compact 000 Martin with Big Sound

Get the comfort of a small body and the convenience of big sound with the Martin 000-18 acoustic guitar. From the toneful and classic combination of a spruce top and mahogany back and sides to the smooth ebony fretboard, the 000-18 offers amazing tone and playability. The 000-sized acoustic has a focused tone that compliments with any style of playing. If you're looking to add a new sound and vibe to your rig, then you need to check out the Martin 000-18 acoustic guitar.

Comfortable Auditorium body style

The forward, balanced tone of the 000-18 comes from its Auditorium body style. This body style provides excellent projection and focus, perfect for competing with a banjo (which was a common combination in the '30s). The Auditorium body style also gives you well-balanced tone, making the 000-18 perfect for recording in your studio.

Modern feel and playability from the Performing Artist neck taper

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 000-18 acoustic guitar. The 000-18 features a modified low-oval neck profile with the Performing Artist 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 000-18 is perfectly suited for both fingerstyle and flatpicking.

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 000-18. 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 000-18 will age gracefully, with enhanced harmonics and greater tonal balance as the years go by.

Martin 000-18 Acoustic Guitar Features:

  • Vintage-inspired acoustic guitar with Auditorium body style and premium tonewoods
  • Punchy voice with excellent projection is perfect for playing with other instruments
  • Rich, timeless tone from the solid spruce top and mahogany back and sides
  • Select hardwood neck has a modified low-oval profile with Performing Artist taper
  • Includes hardshell case

Great instrument...

I purchased this guitar from Tyler Moore. It was a phenomenal deal, and a beautiful piece of work. I'm very proud of it. I had them install the Gold Plus pickup and set the action (more on that later).

The guitar is as good of a build as I had hoped for. Awesome grain in the Sitka is going to age wonderfully. I sold Martins in the 80s and 90s. The 16 and 18 series are my favorites, though I feel secure that I'll one day be after a D-28, as well. There is something about a mahogany instrument that just fits my tone niche. This guitar had the punch of a much bigger guitar, and a clarity that you don't find in lower price guitars. But, that's what Martin is all about.

The action: I was disappointed, in the order, due to the fact that I asked for a LOW almost buzzing action, and it came feeling like a standard Martin Bluegrass setup. That may have been a miscommunication, but it is what it is. So, I filed the lower E down a touch, and put a humidifier pack in the case to regulate it back to the right place. Then, a light tweak on the truss rod got it right where I wanted it.

I guess that is the good part about the new Martins. You can get that low action on it. I owned a 70s D-28, and my son has a 66 D-28. If you wanted them lowered, it is a serious task. But, I was able to get this guitar into a great action in a week. Now it plays great.

The case isn't too bad for this guitar, I think it will be fine, as it fits like a glove. Overall, I do recommend this guitar, and if you are not good at setting up your own guitar, find a local luthier to help you out. You will be amazed at the power this little guitar has to offer you.

Best acoustic I’ve ever owned.

Thanks to Sweetwater and Alan Carter for making this happen!
I've been playing for over 50 years, acoustic and electric. I've always owned dreadnoughts. This is the first 000 size acoustic I've owned. I've own it for a few months now and can't put it down. The sound is pure and balanced. The size and playability is perfect. Although it's smaller, it still has beautiful rich lows and projects surprisingly well. The guitar not only sounds amazing, it's drop dead beautiful. Everything about it is perfect, materials, craftsmanship setup.
I also tried the 00028EC. It's also a wonderful guitar. The V neck just didn't fit my hand. I'm sure some might prefer it though. I can't wait to start gigging with this guitar.
Music background: Semi professional performing for 40 + years.

Delish! Musically Speaking’

Short and Sweet: A dream come true guitar for me. Expensive? Yes, but looks, build quality, playability, and sound' sure put my mind at ease. Comes with a great case' to protect it while it awaits your attention. I had LR Baggs' Anthem Pickup installed and it sounds 'sweet and natural' out of my acoustic amp. A big shoutout to Sweetwater' team members Chris McCown' Joe Stilwell' and David Bell'…thank you!

Beautiful Guitar

Being a complete novice and 70 year old newbie to guitar playing, I feel less than qualified to write a review. One of my high school friends has played his whole life and swears by Martin, and has been guiding me down the path. This instrument in his hands is nothing short of magical! He played all of the oldies, Dylan, CSN, Clapton, and Young. All he could say was WOW! The Martin is beautifully crafted, incredibly light in weight, and an amazing instrument. My finger tips are forming callouses and I am slowly progressing. Thank you Sweetwater for the great service and prompt delivery of my new Martin.

It’s A Martin Guitar Enough Said

First I would like too thank Daniel Moore, my Sales Engineer for years now. He's always on top of his game and represents Sweetwater very well. Also I thank Sweetwater for their fine product line and service too me. Now as for the Martin 000 18. It fitted my playing style too a tee. I love the neck on the 000 18 cause it is very comfortable and fast. The sound is unbelievable very rich and mellow. It has a sound of its own, which I love. I have a Martin D 28 that has it specific sound too. Also a 000 15 SM with its own rich sound. They all have their own personality, which I love. Took a while get use too the D 28 with the big body and neck but with the 000 18 it was right on spot. I could play the 000 18 right then and there but I was used too Classical Guitars, also. Thank You Mr. Martin for your line of outstanding acoustic guitars. None Better. Thanks Daniel and Sweetwater for your professional service too me and my music.
