Martin OM-21: A True Original Acoustic

A true Martin original, the Martin OM is considered by many to be the design that ushered in the modern era of acoustic guitars. Martin unveiled the OM in 1930 as their Orchestra Model — a new body design that departed from the 12-fret designs they had offered since their founding in 1840. The Martin OM offered a 14-fret neck and a 000-inspired body that translated to big, projected tone — ideal for the popular dance hall and orchestra-style performances of the time. The Martin OM-21 of today stays true to the OM of the 1930s, featuring a classic spruce top, rosewood back and sides, and select hardwood neck with ebony fingerboard and modest appointments that keep the price point lower but the sound still at the top. One of the new features of the Martin OM-21 is the Performing Artist neck profile, which features a shallow oval shape with a slightly narrower taper than a typical OM’s neck.

Rosewood and spruce deliver beautiful acoustic tone

You just can't beat the sound of solid spruce and genuine rosewood. For such an affordable guitar, this Martin OM-21 acoustic guitar spares no expense on its tonewoods. You'll love the crisp sound of this OM-21's solid East Indian rosewood back and sides. What's more, the Martin OM-21 is topped with solid spruce, adding rich and mellow overtones into the mix.

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. This OM-21 features a modified low oval neck profile with the Performing Artist taper. The Martin OM-21's 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, the Martin OM-21 acoustic guitar 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 this Martin 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
  • Performing Artist neck taper and satin-finished neck responds beautifully
  • 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

My favorite 6 string

I've owned an OM-21 since I was 14. I played it in my local music shop and that was it. I saved up for a year to buy it. That was almost 30 years ago, and I haven't played a finer 6-string acoustic since. It's been to multiple countries and continents with me. The tone, the neck, the size... they're all perfect. There is a balance to the sound of this guitar I rarely find in dreadnoughts. And the smaller size is so comfortable to hold and play for hours. There's literally nothing I would change about it. Whether you strum chords or play fingerstyle, an OM-21 will be a reliable, inspiring instrument. All your money goes toward the materials and craftsmanship with this guitar. There's nothing showy about it, but the tone is absolutely perfect. If my OM-21 was ever stolen, I'd get another, because it's simply what a 6-string is supposed to sound like.

A masterpiece

How do you even review a piece of arts? For me this guitar tics all boxes of what I ever wanted of a guitar. An incredible tone with a richness and clarity that makes anything you do with it sound great. It is simply the best guitar I have ever heard. Playability is also better than anything I have ever tried. I play a lot finger style and have quite small hands and relatively short fingers which have made me struggle a bit with bigger neck sizes. The slim neck size on the OM-21 is just perfect and makes everything so much easier. If you can afford it, this guitar will never disappoint you. This is an excellent choice you will never regret buying.

OM-21 — Stunning!

Really a phenomenal instrument. Tone is very full and balanced. Bass response great for OM size. Stands up well to moderate strumming and note definition is succinct with fingerstyle play. I had previously tried a middle-road 000-14 which was really good. However, tone quality from this guitar is at a completely different level. Thanks to Chris Sonia for the excellent service and helping secure this instrument and even facilitating an extra multi-point check to ensure no problems prior to shipping. Highly highly recommend!
Music background: Intermediate self-taught.

New Number One

I've been playing guitar for 40 years now. In all this time, I've NEVER played an acoustic guitar that calls my name more than this Martin OM-21. It's everything I've ever wanted in an acoustic. The small body size is absolutely perfect. It's so comfortable and let me tell you, the tone is off the hook. The tone is huge. Pennsylvania craftsmanship at it's finest. The woods used, the craftsmanship, the legacy of Martin.....it's all here folks. I have an HD-28 that I love but this OM-21 is my new number one. It's phenomenal. I have to say, without Mike Harris' help, I wouldn't have known about this guitar. Mike Harris is extremely knowledgeable and without his guidance and help finding this awesome instrument, I wouldn't be writing this. Kudos to Mike and Sweetwater for the best gear and the best service in the industry.
