A Classic OM-28 with a Modern Twist

Martin's OM-28 acoustic guitar is a small-bodied instrument that delivers big sound. This beautiful instrument gives you the bold clarity of a solid East Indian rosewood back and sides plus the exquisite tonal balance of a sitka spruce top. You'll love the ultra-comfortable modified low-oval neck profile with the Performing Artist taper. The OM-28 is constructed just like it's sister, the OM-28E Retro, without the electronics. Add great-playability and a bold, focused sound to your collection with the Martin OM-28 acoustic guitar.

Martin 0M-28 Acoustic Guitar at a Glance:
  • The Orchestra guitar done right
  • Modern feel and playability from the Performing Artist neck taper
  • Rich, timeless tone from rosewood topped with spruce
The Orchestra guitar done right

There's no question that Martin's original Orchestra model has been one of the most influential acoustic guitar styles in modern music history. From its bold herringbone inlays to its hand-selected bone nut and saddle, the OM-28 does more than merely capture the spirit of the original, it revives all of the small details that make this instrument a classic. When you pick up a Martin OM-28, it's like stepping back into guitar history.

Unique hybrid neck profile makes this one comfortable guitar

Carving off the beaten path for Martin, the OM-28 acoustic guitar features a new neck carve. Best described as a solid compromise between the solid feel of a Modified Low Oval profile and Martin's slimmer and faster Artist Series profile, the OM-28 has one of the best all-around neutral-feeling necks you're likely to find. No matter if you have gorilla-sized mitts or the most petite pair of paws, chances are good that you'll feel right at home playing the OM-28.

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-28 spares no expense on its tonewoods. You'll love the crisp sound of the OM-28's solid East-Indian rosewood back and sides, and they look fantastic. What's more, the OM-28 is topped with solid Sitka spruce, adding rich and mellow overtones. Take it from the Sweetwater crew - the Martin OM-28 delivers the tone and playability you want in an acoustic guitar!

Martin 0M-28 Acoustic Guitar Features:
  • The classic OM/Orchestra model acoustic with an updated neck profile
  • Made from a choice selection of tonewoods, including an East Indian rosewood back and sides, a Sitka spruce top, a black ebony fingerboard, and a matching black ebony bridge
  • Rosewood and spruce deliver sweet, bold, clear, and balanced acoustic sound

OM-G! I really like my OM-28! In fact, it's now my only acoustic and may be the last one I ever own. After researching obsessively, I decided I to pull the trigger. I sold my Taylor 414ce to help finance this sweet 000-14 freter. I am impressed! The tone is wonderful and the 000 body is so easy to hold for long periods, along with the .10 gauge strings. I play mostly finger style, as well as some flat picking and this baby is great at both. It's a lifer! The sweetwater guys , Mike W. and Karl L. did such a great job answering all my questions. They really worked hard and helped me to get my first Marin. They were even able to squeeze it in to ship that night and I received it in 3 days (before the weekend)! Thanks guys!

Sweet Stuff

Purchased the OM-28 about two months ago, & I must say: It is smooth . . . what else to expect--a Martin, top of the OM line, over three grand (was sellin' for $2850 a couple of years ago, & kickin' myself for not buyin' then--attribute that to "supply & demand"--tells ya somethin' about this "beauty"-- i.e., this latest OM-28 version with tapered neck has obviously been in demand). The OM-28 offers a richly resonant accompaniment to my other acoustic, a 1957 Martin 00-18 that I purchased in the late 60's for $380 (from a college student--who, btw, had seller's remorse a month later) --the 00-18 is now worth over $3,500. Bottom line--the acoustic Martin: not only an investment but tone that's candy to the ears -- (as if you didn't already know that, right?) Shout-out to Zach Neels (Senior Sales Engineer)--not only expeditious with orders but simply (during the last five years) just a great guy to work with.


I have had several Martin guitars and the tone and playability of this guitar takes a back seat to none of them.

Awesome guitar; superb service!!!

First off,this guitar is a strummer, as well as a finger picker. The lows are substantial enough with clear mediums and angelic highs. I especially love the neck which is very comfortable for large to small hands alike. The construction is first rate as can be expected from a martin guitar. I highly recommend this guitar. I have conducted business with Sweetwater for a couple of years and can honestly say wholehearted that they are # 1 and in a league of there own, right from customer service which does get any better than my sales expert Evan Muli

Why'd I wait so long?

I believe I finally found my ideal guitar. I've always preferred smaller bodied guitars, but most OMs I've played lacked the body and resonance I want in an acoustic. I typically play fingerstyle, which the OM-28 excels at, but this guitar also projects well when strummed. Of course it cannot give you the boom of a dread...but it is incredibly versatile. I've had many Taylors and Larrivees over the years, a Guild and a Yairi, but I always hesitated to pull the trigger on a Martin due to the price. No electronics and few ornate appointments. But this time I went for it--and bought a Fishman Rare Earth Blend pup with mic and I am very happy with the sound of this guitar when plugged in. My last two Taylors were a 714ce and an 814ce--both great guitars in the same price range as the OM-28. I chose them over the Martin due to the on-board electronics and cosmetics. This OM-28 is subtle but looks great. And the sound and playability is second to none.
