Martin\u2019s CS-OM-13<\/b><\/h1>\n<p style=\"text-align: justify;\">The CS Series of Martin guitars has entered its third year with the introduction of a new model for 2013. And for the first time, the master craftspeople at Martin\u2019s Custom Shop have added an Orchestra Model to the line, the CS-OM-13.<\/p>\n<p><iframe loading=\"lazy\" src=\"http:\/\/www.youtube.com\/embed\/65k04d_XDeQ\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<figure id=\"attachment_452\" aria-describedby=\"caption-attachment-452\" style=\"width: 88px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/csom13.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-452\" style=\"border: 0px none;\" src=\"https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/csom13.jpg\" alt=\"csom13\" width=\"88\" height=\"207\" \/><\/a><figcaption id=\"caption-attachment-452\" class=\"wp-caption-text\">CS-OM-13<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Features include: Madagascar rosewood back &amp; sides, high altitude Swiss Spruce top, scalloped Golden Era style 5\/16\u201d top braces, exclusive mix of Adirondack and Sitka spruce bracing, quilted bubinga body and fingerboard binding, exclusive pearl-bound, scalloped red diamond fret markers, Madagascar rosewood bridge plate.<\/p>\n<p style=\"text-align: justify;\">With its combination of contemporary design and historical features, the CS-OM-13 offers new dimensions in tone and aesthetics, while emulating some of the best, traditional Orchestra Models ever created. Built for resonance and responsiveness, it is ideal for nuanced playing in the deft hands of a master fingerstyle guitarist, but it can just as easily hold its own when under the pick-and-strumming required for the cowboy songs of Gene Autry and Roy Rodgers, who first popularized the OM guitars of the early 1930s.<\/p>\n<p style=\"text-align: justify;\">Fred Greene, VP of Manufacturing at Martin designed the guitar. He stopped by to say hello when we were at the Martin factory, in Nazareth, Pennsylvania, to test drive the new prototypes, the day they were unveiled at the Winter NAMM show out in California. He said the Custom Shop team wanted to build on the legacy of the OM platform and show that C.F. Martin\u2019s legacy continues to progress. \u201cThe premise of all CS models has been to continue to evolve classic Martin designs and tonal characteristics. We wanted a guitar that felt welcoming and familiar without looking or sounding like something we had already done.\u201d<\/p>\n<h2 style=\"text-align: justify;\"><b>Materials<\/b><\/h2>\n<p style=\"text-align: justify;\">The entire guitar is built with hot hide glue, normally an expensive upcharge at Martin. The back and sides are made from solid <b>Madagascar rosewood<\/b> that comes with a high gloss finish. Madagascar rosewood offers cosmetic beauty similar to Brazilian rosewood while including grain patterns found nowhere else. And for sound, it has dazzling high harmonics singing over its distinctive tonal pallet, which might be described as a combination of open mahogany clarity and rich rosewood complexity.<\/p>\n<figure id=\"attachment_453\" aria-describedby=\"caption-attachment-453\" style=\"width: 145px\" class=\"wp-caption alignright\"><a href=\"https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/back.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-453 \" src=\"https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/back.jpg\" alt=\"CS-OM-13 Madagascar rosewood\" width=\"145\" height=\"181\" \/><\/a><figcaption id=\"caption-attachment-453\" class=\"wp-caption-text\">Madagascar rosewood<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">The top is also finished in high gloss and made from \u201c<b>high-altitude Swiss spruce<\/b>\u201d, which Martin unveiled on some of the 2013 models. Although Martin apparently used some spruce from Switzerland on some recent guitars, under the name &#8220;European spruce,&#8221; the spruce on this model is reputedly harvested only during the winter months, before the new moon from the snows of the Swiss Alps. Violin makers feel this spruce provides increased stiffness and dynamic range when milled to lighter weights than other Alpine spruce, or Carpathian spruce. All are the same species but come from different microclimates.<\/p>\n<p style=\"text-align: justify;\">Comparisons have been made with the spruce used on Stradivarius violins and celli. It is now believed that particular spruce grew during an abnormally cold period in European history known as the \u201cLittle Ice Age,\u201d which resulted in consistent, slow growth and low sap content. Due to climate change, those hoping to get this species of spruce today with qualities similar to the Stradivarius spruce must look elsewhere than the forests of Italy where it originated. But scientific research has suggested it can still be found in climates with lengthy but stable winters. One such choice is the <a href=\"http:\/\/www.tonewood.ch\/moonwood.html\">&#8220;moon wood&#8221; from Switzerland.<\/a><\/p>\n<p style=\"text-align: justify;\">The soundboard on the CS-OM-13 prototype I played reminded me of Carpathian, as it had a bit more definition and \u201cping\u201d to the fundamental notes, and a bit less of the warm pastel glow in the resonating undertone heard from the Italian Alpine spruce used on other Martins. It displays a uniform, buttery complexion, with tight grain, that is evenly spaced and very straight, with loads of shimmery cross grain. Other examples of this model sport noticeable bearclaw anomalies, also known to woodworkers as hazelficte, thought by some luthiers to signify older, stiffer wood.<\/p>\n<p style=\"text-align: justify;\">The hand-fitted, dovetail neck has typical Martin OM widths of 1-3\/4\u201d at the nut and 2-1\/4\u201d at the 12th fret. And it is matched with modern OM string spacing of 2-1\/4\u201d, which may seem narrow to vintage guitar fans, but it should appeal to a wider population of modern players.<\/p>\n<p style=\"text-align: justify;\">The neck itself has a satin finish, and is made from one piece of solid <b>Big Leaf mahogany<\/b> reinforced with a two-way adjustable truss rod. And like the other CS models, it is carved and shaped entirely by hand, to what has become known as the Custom Shop #1 profile.<\/p>\n<p style=\"text-align: justify;\">To this player\u2019s hand, I would say the CS neck is inspired by traditional Martin necks, but without the bulk in the upper frets, or the pronounced V. Yet it still feels related to a vintage Martin more than the \u201clow profile\u201d or \u201cmodified low oval\u201d found on other modern Martins. I might have named it the \u201clow vintage\u201d profile. One interesting feature, the stain on the mahogany is considerably lighter than many Martins, and almost caramel in appearance when matched with the dark, earthy stain used on the rosewood body. This allows the guitar to fit in visually with the earlier CS models, the first of which, the CS-21-11, had a light-weight neck of Spanish cedar.<\/p>\n<p style=\"text-align: justify;\">In a combination of traditional and modern design, the <b>black ebony <\/b>bridge is cut in the 1930\u2019s shape, but has a short, drop-in saddle to work more easily with an under-saddle pickup. The fingerboard is made from the same ebony and the fret markers were designed specifically for this model. They are scalloped diamonds of a dark red hue that look like polished spiny oyster stones, but are replicas made of a stronger, synthetic material created from crushed gemstones. Each of the seven diamonds is bound with glinting, polished abalone. They get shorter and wider as they go up the neck, to match the spacing of the frets, with the outer points of the diamond always directly inside of the 2nd and 5th strings. So, at the 3rd fret, the first diamond is as wide as it is tall, with an ample piece of red stone. But at the 15<sup>th<\/sup> fret, the final diamond is a long, narrow cat\u2019s eye, with a thin slice of red winking out from the pearl outline. The overall effect is quite beautiful.<\/p>\n<figure id=\"attachment_455\" aria-describedby=\"caption-attachment-455\" style=\"width: 248px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/topuse.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-455 \" title=\"CS-OM-13 top inlay\" src=\"https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/topuse.jpg\" alt=\"topuse\" width=\"248\" height=\"190\" srcset=\"https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/topuse.jpg 360w, https:\/\/onemanz.com\/guitar\/wp-content\/uploads\/sites\/2\/2013\/04\/topuse-300x230.jpg 300w\" sizes=\"auto, (max-width: 248px) 100vw, 248px\" \/><\/a><figcaption id=\"caption-attachment-455\" class=\"wp-caption-text\">New inlays<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">The pearl ends there and they wisely used the Style 28 rosette done in traditional wood fiber, which is also used for the purfling around the body. The Golden Era OM pickguard is made in high-quality Delmar style, of faux tortoise shell. To continue the theme of old meets new, the tuners are open-back nickel Waverlys, but with snakewood buttons that set off the headstock\u2019s Madagascar rosewood faceplate very nicely. And the C.F. Martin &amp; Co. decal is done in silver, as with all guitars of the CS Series.<\/p>\n<p style=\"text-align: justify;\">The <b>quilted bubinga<\/b> wood that binds both the body and the fingerboard is gorgeous, with a light orangish-red tint and dark, brick red accents that tie together the colors of the mahogany neck, the rosewood body, and the oyster stone inlays to unify the overall aesthetic. It is just one more feature that sets this Martin apart, and declares that the Custom Shop has produced a fingerstyle guitar that belongs in exclusive boutiques alongside the instruments from any small-shop luthier building today.<\/p>\n<p style=\"text-align: justify;\">After the prototypes were finished, Fred Greene was quite pleased with the final motif. \u201cThe warm red hues of the bubinga binding against the rich Madagascar rosewood, combined with the new twist on our diamond inlay pattern, really captured the classic and modern vibe we were aiming to achieve.\u201d<\/p>\n<h2 style=\"text-align: justify;\"><b>Unique Aspects of Design <\/b><\/h2>\n<p style=\"text-align: justify;\">But for all its top shelf looks, some of the most interesting features are hidden under the hood. The CS-OM-13 has a Madagascar rosewood bridge plate (!), a first for Martin. They also feature a combination of different spruce for the bracing. The X brace is made from stiff Adirondack spruce, while the adjacent traverse braces and tone bars are all made from softer Sitka spruce. Just as interesting to me, they went with 5\/16\u201d top bracing, instead of the thinner 1\/4&#8243; bracing used on other Martin OMs since they reintroduced the design to their catalog in the 1970s. But the braces feature Golden Era style scalloping, which has more pronounced scoops to the carving, reducing the overall mass of each brace. To my knowledge, this is the first time 5\/16\u201d Golden Era style bracing has appeared on a non-dreadnought Martin with a 14-fret neck.<\/p>\n<p style=\"text-align: justify;\">Although the original OMs from the 1930s had 1\/4&#8243; bracing, the width used for the main X brace was actually 5\/16\u201d. The first modern Martin to use this same hybrid bracing was a limited run made by the Custom Shop for Gryphon Stringed Instruments of Palo Alto, California, and reproduced the specs of the very first 14-fret Martin, created in 1929 for renowned banjoist, Perry Bechtel. The mixing of the spruces used to brace the CS-OM-13 seems to be an experiment aimed at achieving similar top dynamics, by employing brace wood of different flexibility rather than braces of different widths. As with all the CS models, the sound of this guitar is not quite like any other Martin, and the unique approach to the bracing is at least partly responsible.<\/p>\n<p style=\"text-align: justify;\">Greene explained it this way, \u201cThe idea of using different spruce species was actually inspired by wine makers who often blend different varietals of grapes to soften or balance their wines. Blending spruce species to create unique tonal properties was an area of design that we felt was underutilized in guitar design. Add a madi bridge plate to recipe and you\u2019re suddenly in uncharted waters.\u201d Similar metaphors of blended wines have occurred to us at One Man\u2019s Guitar when describing the tonal differences in different species of rosewood. Apparently great minds do think alike.<\/p>\n<h2 style=\"text-align: justify;\"><b>Playability and Tone<\/b><\/h2>\n<p style=\"text-align: justify;\">Eyes widen as one picks up the CS-OM-13, and they realize how the guitar is noticeably light of weight. Ultra-light, might be a suitable term for this OM, and as a result it has dynamics shifted decidedly to a lighter touch and nuanced style of playing. It is extremely responsive, putting out a lot of sound from the slightest effort. The balance across the six strings that made OMs famous is certainly there. The fundamental notes are nicely defined, while sitting over that \u201clittle, old wooden box\u201d effect one hears in many vintage guitars, as if it has a built-in reverb unit. It is bright, open, airy and ringing. But that air below and around that top voice is pregnant with resonating tone.<\/p>\n<p style=\"text-align: justify;\">When played slowly with sustaining notes, sympathetic harmonics ignite all over the place. The bass strings, struck and left hanging in the air, conjure waves of overtones from the trebles, where an angel of great purity eventually appears on high to grace the harmonic choir. And down in the undertone of the lows and mids is found the spacious, but cloudless bottom end which, along with the reflective treble chime, sets Madagascar apart from the other rosewoods.<\/p>\n<p style=\"text-align: justify;\">Madagascar rosewood is the anointed heir to the legendary Brazilian rosewood that is now so rare it is cost prohibitive. Their tonal properties are similar, with Madagascar rosewood offering slightly less complexity than Brazilian and bit more brightness, with its harmonic spectrum shifted a ways out of the lows and low-mids and into the mids and trebles. So it has crisp, chimier notes and a somewhat drier, more open bass than other overtone-rich rosewoods. I absolutely love Madagascar rosewood as a tonewood and own three Martins made with it, compared to one in Brazilian. And I will declare here and now that this new Swiss spruce is a very good match for Madagascar rosewood.<\/p>\n<p style=\"text-align: justify;\">Spruce can add some aural filters to the sound of a tonewood. But mainly it accentuates or brings out certain qualities already there. This spruce is almost as reflective and quick as Adirondack spruce, so it brings out the Madagascar chime and definition very well, while that creamy quality in the undertone, heard in European spruce, but lacking in Adirondack, helps pull some warmth up out of the bottom end. Those of you lucky enough to play or own one of those recent Eric Clapton models, made with Madagascar rosewood and the Carpathian spruce tops, will understand just what I mean.<\/p>\n<p style=\"text-align: justify;\">In some respects, and despite all its progressive and experimental features, this new CS model sounded more \u201cvintage\u201d in its overall voice than many vintage reissue guitars. I thought it was absolutely lovely; woody, chimey, glowing, and very, very pretty.<\/p>\n<p style=\"text-align: justify;\">No guitar does everything equally well, and the dynamics of this guitar excel under a light touch, responding brilliantly to the slightest change in attack or string pressure. But it therefore does not hold up as well under heavier attack. It is perfectly good for strumming, playing leads with a flatpick and even full out Bluegrass flatpicking, up to a point. Once the strummer or flatpicker puts some serious muscle into their playing, the voice begins to compress, and even though it may get louder, it does not increase in genuine power or bass response the way larger or sturdier guitars do. And that is exactly how a Martin OM from the 1930s responds to heavy handed playing, as do the vintage 000s.<\/p>\n<p style=\"text-align: justify;\">And like those old-timers, a player simply doesn\u2019t need to play this guitar that hard. It is so alive that the resonant sweet spot is reached with very little effort and provides ample volume and projection without the player having to force the issue. Players unused to such dynamics may feel they have to keep their foot on the break to not overdrive the top. But once one relaxes and allows the guitar to guide the player to \u201cthe zone of optimum response,\u201d they will likely come to enjoy laying back and letting the instrument do all the work.<\/p>\n<p style=\"text-align: justify;\">The thing practically breathes on its own. Only time will tell if the top opens up to allow the kind of supernatural attack ceiling found in the ultra-light, pre-war Martins. Again we find a meeting of the traditional and the nouveau. Even if it has the Madagascar\/Alpine chime that didn\u2019t exist in the 1930s, it has a lot in common with the old OMs and 000s when it comes to woody resonance, responsiveness and sensitive dynamics.<\/p>\n<p style=\"text-align: justify;\">I would not say the overall voice is identical to a typical OM, or a typical 000, but it offers a bit of both. And that, I think, is where the unique bracing comes into play. The OM-ness shows up in the resonating tone that glows out from the body during light, sustained playing, and also in the impressive projection under light attack that can be attributed to the string tension of a long-scale neck on the Auditorium size top.<\/p>\n<p style=\"text-align: justify;\">The 000-ness shows up in how punchy the notes are when played with more power and how they pop out proportionate to the amount of snap in the strings from the picking hand, and in how the voice doesn\u2019t break up under a heavy attack, so much as compresses during full strumming. The six strings press into a single, integrated sound like a fist of energy gathered in the midrange that is then shot out from the sound hole, its sympathetic overtones left a bit in the background like smoke around a canon. That is the hallmark of 5\/16\u201d bracing. Typical OMs don\u2019t tend to do that. With lighter bracing, energy dissipates out around the body, so the fundamentals spread out more and the voice projects at a wider angle, with less midrange punch, but with more of an accompanying harmonic glow around the whole.<\/p>\n<p style=\"text-align: justify;\">Ultimately, it is a matter of subtle differences, since a 000 and an OM have the same size body and top. And with various design changes through the years, there is a lot of gray area when it comes to what defines one or the other. The CS-OM-13 offers a unique blend of the best features of both the traditional OMs and their close cousins, the 14-fret 000s. Having 5\/16\u201d scalloped bracing that includes a stiff Adirondack center, and more-flexible Sitka spruce for the outer edges, seems the likely candidate behind the hybrid tonal properties.<\/p>\n<h2 style=\"text-align: justify;\">Conclusion<\/h2>\n<p style=\"text-align: justify;\">It all makes this guitar a very good choice for someone who plays solo fingerstyle pieces, wants an alive and resonating vehicle that will take full advantage of the harmonic possibilities in alternate tunings, but also wants to play lead accompaniment with other guitarists and needs something with midrange pop and the definition necessary to clearly cut through the chord progressions, without sacrificing too much in the way of harmonic overtones. Given the tonewoods and special bracing, there would be little redundancy if this guitar was added to a collection that contained other Martin OMs or 000s.<\/p>\n<p style=\"text-align: justify;\">According to Fred Green, \u201cTonally, (Martin\u2019s) goal was to create the ultimate fingerpicking OM, delicate, sensitive, and balanced with enough headroom to achieve the dynamics serious players demand. This guitar was designed with serious players in mind.\u201d<\/p>\n<p style=\"text-align: justify;\"><strong>Overall<\/strong> &#8211; the CS-OM-13 is a tremendous success, while remaining a fingerstyle-first sort of instrument, and a welcome addition to the innovative Custom Shop\u2019s line of guitars. Like its CS predecessors, it brings together bold new materials and features, along with vintage vibes and finely honed construction techniques. Fred Greene and the workers at Martin\u2019s Custom Shop have created an admirable addition to the CS Series and Martin\u2019s growing catalog.<\/p>\n<p style=\"text-align: justify;\"><b>The Good<\/b> \u2013 A gorgeous and lovely fingerstyle guitar, with exquisite responsiveness, that can hold up to moderate strumming, and offers a hybrid tone with the harmonic glow of an OM and the punchy mids of a 000, a comfortable, long-scale OM neck, and sumptuous boutique-esque appointments, all at a ridiculously reasonable price. I shudder to think of the sticker shock, if this exact guitar was ordered as a one-off custom by a working guitarist.<\/p>\n<p style=\"text-align: justify;\"><b>The Bad<\/b> \u2013 Some players may find things shifted too far into the delicate and pretty side of the spectrum. The voice compresses and can be overdriven under a heavy hand, without too much effort. This is not the mini-dred OM from the Standard and Vintage Series, but rather an ultra-light fingerpicker with ultra-responsive dynamics.<\/p>\n<p style=\"text-align: justify;\"><b>The Ugly<\/b> \u2013 They are only making this model during 2013, one guitar at a time, in the same Custom Shop that is building the Authentic Series and custom orders for dealers and their customers. So you better call around if you want to see one these in person before they are all snatched up by private citizens who appreciate a great guitar when they play one.<\/p>\n<p>And that is one man&#8217;s word on&#8230;<\/p>\n<h3><strong>Martin CS-OM-13<\/strong><\/h3>\n<p>Revised 04\/26\/13<\/p>\n<p>Thanks go out to Mike Brennan for the fact checking!<\/p>\n<p>Other Martins reviewed at One Man&#8217;s Guitar include:<\/p>\n<p><a href=\"http:\/\/wp.me\/P3p2sf-11j\" target=\"_blank\">Reviews of Custom Shop Series Martins<\/a><\/p>\n<p><a href=\"https:\/\/onemanz.com\/guitar\/reviews\/acoustic-guitars\/martin\/ceo-7\/\" target=\"_blank\">CEO-7<\/a><\/p>\n<p><a href=\"https:\/\/onemanz.com\/guitar\/reviews\/acoustic-guitars\/martin\/om-42-deep-body\/\" target=\"_blank\">OM-42 Deep Body Custom<\/a><\/p>\n<p><a href=\"https:\/\/onemanz.com\/guitar\/reviews\/acoustic-guitars\/martin\/martin-om-30db\/\" target=\"_blank\">OM-30DB Pat Donohue Model<\/a><\/p>\n<p><a href=\"https:\/\/onemanz.com\/guitar\/reviews\/acoustic-guitars\/martin\/authentic-series\/\" target=\"_blank\">Authentic Series<\/a> &#8211; in-depth reviews of all of them<\/p>\n<h4>Read more about C.F.
