Definitive Acoustic Tone from a Legendary Martin

The classic Martin D-18 acoustic guitar will take you back to the days when acoustic guitars were king, and players depended upon rich tone and acoustic projection alone to convey their songs. Pick up Martin's absolutely amazing D-18 and you'll be captivated by its big, full tonality, its beautiful sonic detail, and its vintage-tinged looks. The D-18 gives you the classic Martin guitar experience, with a dreadnought body, a 14-fret design, and beautiful tonality to match its looks. Its solid Sitka spruce top and mahogany back and sides provide the foundation for stunning sound, and the Martin D-18 acoustic guitar will only sound better as it ages.

Martin D-18 Acoustic Guitar at a Glance:
  • Classic, "just right" Martin tone
  • The choice of session guitarists for decades
  • Part of modern music's history
Classic, "just right" Martin tone

Ask anyone who knows their bluegrass why the Martin D-18 has been a top choice for serious performers. It's because the D-18's iconic tone sits "just right", cutting through and holding its own without overbearing other instruments. Whether you're playing solo, or in a full bluegrass jam, your D-18's rich tone will always be heard without fighting with vocals, or covering up the low-end impact from the bass player.

The choice of session guitarists for decades

The Martin D-18's "just right" tonality is just as useful in your studio as it is on stage. Just ask any recording engineer that's been in the business for a couple decades: the D-18 has an uncanny ability to set itself into any mix nicely, with a minimum of processing. Sure, that jumbo-body rosewood guitar looks great, but you'll be rolling off low frequencies and carefully adjusting compressors to prevent it from getting too boomy or indistinct in the final mix. Just grab your Martin D-18, point your favorite small-diaphragm condenser mic at the 12th fret, and you've got a sound that practically mixes itself.

Part of modern music's history

You've already heard the sweet sound of the Martin D-18 more times than you probably realize. That's because it was the choice guitar of legends such as Clarence White, Elvis Presley, and many more. Even Andy Griffith played one on The Andy Griffith Show. The Martin D-18 is a perfect example of an instrument that became iconic purely based on its tone and craftsmanship.

Martin D-18 Acoustic Guitar Features:
  • An iconic piece of Martin guitar history, with a focused tone that sits well with a wide variety of instruments
  • Solid Sitka spruce top for amazing projection and great note definition
  • Mahogany back and sides for a well-balanced tonal range
  • Focused low frequency response that sounds tight, never boomy
  • Hardshell case included

Choose the Martin D-18 acoustic guitar for classic tone with remarkable craftsmanship!

Thanks Martin!!

One of the best moves Martin has made is the remake of the time honored D18. No longer straight braced with a 1 11/16th inch nut width. The new D18 has scalloped forward shifted bracing and the new high Prefomance neck with 1 3/4inch nut width. This D18 has the deep base of the vintage golden era Martins but remains well balanced not over powering the trebles. It has a beautiful high end and the smooth playing up the fretboard now made much easier with the High Preformance neck and a 1 3/4in nut width. Gone is the black Pickguard replaced with a Delmar tortoise pickguard. The ebony fretboard is smooth and feels wonderful and the set up out of the box was a perfect 3/32in and 2/32in at the low E and high E 12th fret. Plus the D18 now comes with a bone saddle and bone nut the only downer for me was the black plastic bridge pins which I replaced with ebony bridge pins. Martin also upgraded the grade of Sitka Spruce used for the solid top which is a major reason for the vintage sound that now is closer to the old original D18's of the 30's , 40's and 50's. I didn't buy my D18 at Sweetwater as I have most of my acoustics due to the fact that when they are in stock at Sweetwater they are sold out in no time so I had to search for a dealer that had one. Sweetwater stil is my first choice however when I am looking for a new acoustic..The new D18 is one of the best acoustics I have played in a long time and wil only get better with age if you love Martins this is a must have acoustic guitar.

Martin D-18

I purchased this from a local dealer, it was a display model. However that did not detract from it's ability to blow me away when I played it. The ease of playing it suprised me, being new to playing the guitar this was my first purchase of a high-end guitar. I would recommend this to anyone beginner or advanced player. GET IT NOW!!!!!!!
