Martin Tone and Style You Can Enjoy for a Lifetime

While the Martin OM-21 acoustic guitar has all the sonic soul you'd expect from a top-shelf Martin, its sleek neck with Performing Artist profile has the modern feel that many Sweetwater guitarists prefer. In classic Martin fashion, the OM-21 balances elegant appointments with time-proven construction methods to bring you an instrument you can cherish for a lifetime. Something about Martin guitars just makes you feel good, as if Grandma's baking a fresh apple pie just for you - experience it for yourself, with the Martin OM-21 acoustic guitar.

Martin OM-21 Acoustic Guitar at a Glance:
  • Rich, timeless tone from rosewood topped with spruce
  • Modern feel and playability from the Performing Artist neck taper
  • Well-suited for both picking and fingerstyle
Rich, timeless tone from rosewood topped with spruce

You just can't beat the sound of solid spruce and solid genuine rosewood. For such an affordable guitar, the Martin OM-21 spares no expense on its tonewoods. You'll love the crisp sound of the OM-21's solid East-Indian rosewood back and sides, and they look fantastic. What's more, the OM-21 is topped with solid Sitka spruce, adding rich and mellow overtones. When you imagine what an acoustic guitar is supposed to sound like, this is it!

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 OM-21 acoustic guitar. The OM-21 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.

Well-suited for both picking and fingerstyle

While every guitarist has their own preference, most guitarists at Sweetwater will agree the OM-21 is equally suited for both fingerstyle and flatpicking. Its 1.75" nut width gives you that extra bit of string spacing that really helps fingerstyle players, without being so wide that you can't play lead runs with a pick. Get the OM-21 in your hands, and we're sure you'll be impressed no matter how you play it.

Martin OM-21 Acoustic Guitar Features:
  • 000-14 fret acoustic guitar with timeless Martin tone
  • Incredibly smooth and fast feel, thanks to the Performing Artist neck taper and satin-finished neck
  • Rich lows, detailed mids, and smooth highs from the rosewood body topped with spruce
  • Expect a lifetime of reliable performance thanks to premium components like the real bone nut and saddles
  • Hard case included
It's hard not to feel good when you're playing the Martin OM-21!

My Favorite Martin

I have vast collection of high end guitars and own quite a few Martins. The Om21 is by far my favorite guitar I own by far. The raw beauty of this guitar is stunning. The guitar is set up to perfection and plays effortlessly. I am pleased that Martin put all of their attention into the woods instead of unnecessary bling. The guitar has decent volume as well. I am primarily a strummer, although it does not have the volume of a dreadnought, it can still project! I feel sorry for my other guitars because they will be put away for a while while I enjoy this beauty.

Sweetwater is there for you

Frankly I wasn't happy with the fit and finish of the first OM-21 I was sent. I could go into detail but succinctly, I was disappointed. But all I had to do is send an email to my Sweetwater Sales Engineer, Nick LaMendola, and explain to him my dissatisfaction and a replacement was on it's way. I have to say I was disheartened to have to send this guitar back because it sounded and played wonderfully. But the replacement is a beautiful example of Martin craftsmanship and sounds and plays just as good. It has an amazing range of highs to lows and incredible sustain that I wasn't expecting from an OM size guitar. The more I play it the more it teaches me about playing the guitar; there are so many nuances and subtleties to discover.Looking at it is like savoring a fine work of art; which it is. It is woods are beautiful and the smell sticks in your memory long after you've closed the case, really nice case, and walked away. I like the subtlety and understatement of the tortoise binding and the aging toner sets this guitar apart. The open machines finish off the "cut above" look of this guitar.Sweetwater and Martin have made me a very happy man.

OM-21 is a Great Deal

After playing my 1969 D-18 all of these years, in 2013 I bought an OM-21. I was use to the D-18 mahogany / sitka spruce sound but when I picked-up the OM-21 being a rosewood / sitka spruce guitar in the OM body style, it was a big WOW. While the base is a tad lighter than the D-18 dreadnought, the OM-21 had beautiful sweet and rich tone and with the redesigned neck, it is a joy to finger pick. Basically it is the same body as an OM-28, 000-28, but the OM series has the long scale neck (000 has the short scale) and it has a teardrop style pick guard whereas the 000 has the regular style. I like the base response of the OM better than the 000 series. Now for the best part - you get the same sounding guitar as the OM-28, but because the OM-21 has less fancy apportionment's, it is less money. I also found out later that the OM-21 is one of my local music store's best selling Martin. On my D-18 I switched to Martin Retro monel strings - a game changer for a mahagony guitar, but for the OM-21 I stayed with Martin SP PB Life Light strings - just so sweet and rich on the OM-21.
