Introduction
When I completed the purchase of my second Collings, a lovely guitar inspired by Gibson’s 1930’s era L-00, I thought I was pretty much done acquiring guitars. My six guitar collection included two resonators (one being electric), two electrics (one being a hybrid acoustic/electric, and two acoustics. But I wasn’t really done. There were two remaining issues affecting my sense of guitar balance and purpose:
First, my hybrid, semi-hollow bodied Taylor T5z, was going for long periods without being played, and that’s a red flag warning that it may be time to go. In the end it’s a niche instrument best for switching back and forth between acoustic or electric tonalities depending upon the tune being played. It’s most suitable for a gig where you only want to bring one guitar, which is not a dilemma I ever find myself in. The truth was, if I wanted to play electric, I had a far better instrument (Collings I-35) to do the job, and there was no way the T5z could match the sonic performance of the Collings acoustics in my stable.
Secondly, I’ve found myself playing a number multiple tunings on my acoustic guitars, including standard, Drop D, and Skip James’s Cross Tuning. Further, there was a Chris Smithers Open D tune that I wanted to take a run at. My experience is that guitars like to settle into a specific tuning so it’s best not to be frequently changing the tunings on a single guitar. For this reason, I began thinking that it might be nice to have a third acoustic guitar at my disposal!
Consequently for the two aforementioned reasons, I decided to eventually trade the T5Z one day in the future. In preparation, via their online process, Dave’s Guitars give me a trade-in value so I knew what I had to work with. Not surprisingly, I was going to take a haircut on a trade, but that’s the guitar business. At first I thought I might swap the T5z out for an American Professional Stratocaster at my local shop, but I was reminded during that Strat’s audition that I was not, at some fundamental level, a Strat player and my Collings Electric really met all my needs, so dumping off the T5z was put onto the back burner for a while.
A Rare Martin Guitar Finds Me
I take lessons weekly at my local guitar shop and it’s not unusual for the former store owner Bob, now store consultant, to greet me and show me some new guitar arrival that might be of curiosity. Most of the time the guitars, usually recent trade-ins, do not arouse my interest. But a couple of weeks ago, Bob dropped a dreadnought into my lap and explained that it was a pre-owned “Martin Authentic” built to the exacting specifications of a vintage 1937 Martin from the golden age of dreadnoughts. The guitar was in immaculate condition too and had been owned by a collector who’d passed away. His son traded the Martin in for a Taylor 814ce. So much about guitar acquisition is driven by idiosyncratic personal taste.
Initially, the guitar Bob placed in my hands was not of interest to me. For years, I’d been playing smaller bodied guitars, not a Howitzer sized dreadnought. Yes, my first two guitars, in a former lifetime, were dreads, but when I gave up on bluegrass flat picking and took up finger-style I moved to 000’s, OM’s and other smaller sized instruments. Further, I’d never been that enamored by Martin’s tonality, fit/finish and general appearance for the cost involved. But this guitar was different, sounding and feeling unusually interesting to me! Perhaps this guitar’s tone appealed to my ears because it was seven years old and had “opened up,” or maybe because the vintage “hand-built” construction techniques employed by Martin’s exclusive Custom Shop appealed to my sense of design aesthetics. Finally, the combination of rare tone woods, specifically an Adirondack spruce top with Madagascar rosewood back and sides produced a tone I’d never experienced before. It was in contrast to the Martins I’d played in the past that required really digging-in to the strings to get a decent sound. As a finger style player, my touch was generally too light to elicit magic from a Martin dreadnought. I noodled around with the guitar for a while and then went to my lesson. Afterwards, on the way out, I glanced at the Martin again hanging on the wall and thought that it might be a nice complement to the Collings acoustics I already owned, particularly for the alternate tunings I like to use.
The next day, I went back to the shop and played the Authentic again for quite a while and found it even more appealing especially since Bob replaced the existing strings with some new ones. At some point, I played the guitar into a Shure SM-57 mic plugged into a Genzler Amp to better hear it and then went home to think about it some more. Finally, the next day which was a quiet rainy Saturday, I went back to the shop with my T5z, made the trade, and purchased the Authentic. The combination of the trade along with a considerable reduction from new because the guitar was pre-owned brought the price down to something reasonable. Current new versions of the Authentic are far more pricey than I’d be willing to spend, so I feel fortunate.
Overview of the Martin 1937 Authentic D-28
To the right, you can see the Authentic. It is a formidably large guitar. Both the size and depth of the body were designed to produce a large sound. In short, the Martin Company designed the guitar to meet the needs of a popular Hawaiian slack key player (open tunings) in the early part of the 20th century. It was some time later in the 1930’s, that the Martin Company decided to begin regularly producing this large guitar and named it the “Dreadnought.”
By the time of the Second Folk Revival in the late 1950’s and early 1960’s the Dreadnought guitar became the “go to” size for acoustic players. The Martin brand was one of the most prized among those large guitars, especially, the mahogany (back and sided) D-18 and the rosewood D-28.
For more background on Martin Dreadnoughts, you may enjoy the following wonderful film:
In the case of my guitar, the D-28, it has over the years, for a variety of reasons, been modified in terms of woods, bracings, and neck designs, still maintaining its general specifications. Because of a combination of rare aged woods and design features such as the hot hide glues used in the olden days, wood thicknesses, and placement of bracings, the 1937 era D-28 is considered a “high-water” mark in Martin Guitar design, and people will pay hefty sums for that vintage. Given that an original ’37 Martin D-28 is far beyond the price range of most guitar players, Martin, in the recent past, responded by producing a Custom Shop rendition of the ’37 that comes as close as possible to the original instrument. I’ve read that they took their museum specimen of the ’37 to the Smithsonian for detailed medical-technology imaging and analysis to generate the specs to manufacture an exact replica. Other than the substitution of Madagascar Rosewood for the practically unobtainable Brazilian variety, the guitar comes as close to the original ’37 as is technically feasible, hence the moniker, the “Authentic.”
Though I was certainly familiar with the value wealthy players placed on rare vintage guitars, up until the time Bob dropped the Authentic into my lap, I was unaware of Martin’s production of a more affordable “authentic/vintage” guitar. Below you can see a short YouTube film of Steve Earle speaking about his 1935 Martin D-28, which is also from the golden era of dreadnoughts. He refers to the ’35 as the holy grail of Martins. Earle’s enthusiasm for that guitar speaks to the motivation behind the Martin Company attempting to reproduce authentic versions of the past.
In addition to the singular sounds emanating from this combination of wood and steel, there is a perceived inherent beauty with this guitar connected to its decades long history as one of popular music’s most essential instruments. From the CF Martin & Co. decal on the headstock, down the mahogany neck, to the herringbone purfling surrounding the soundboard, as well as the tortoise colored pick guard, the guitar projects a culturally constructed aesthetic intertwined with the likes of Tony Rice, Elvis Presley, Eric Clapton, Hank Williams and Bob Dylan among others.
Still, as an observable object in visual space, the D-28 body is not really proportioned to the dictates of classical aesthetic beauty. A more classically designed guitar would have a narrower waist separating a smaller upper bout from the larger lower one. In many respects the Martin dreadnought is a big box with curved corners attached to a long neck, but its awkwardness relative to classical proportions is today considered an essential part of its beauty.
The Headstock
Before I got annoyed with their heavy-handed marketing and later became disenchanted with their tone, I was the owner of several higher end Taylor guitars. I bring this up because In comparison to typical Martin D-18’s and D-28’s, my similarly priced Taylor’s were appointed way more nicely with wooden bindings and purflings, as well as abalone inlays in the rosette, fretboard and headstock. I was completely put off by the “prosaic” C.F. Martin decal on the headstock, wondering why Martin would not use an inlay in the headstock on their flagship (and expensive) guitars.
My opinion about superficial guitar “surface” bling changed after acquiring two incredible sounding and rather simply appointed Collings guitars. I finally realized that the nice features Taylor offered were all well and good, but the guitar’s tone was by far the controlling factor for the instrument’s worth and value to me. I came to appreciate simplicity in appearance when accompanied by superior tonal output!
Given my new frame of reference, I am delighted with the Authentic’s headstock. Although I myself would not recognize the subtle differences between other more modern D-28’s, the headstock of the Authentic is shaped in thickness and taper as the ’37 was originally made, in this case with a Madagascar rosewood veneer instead of Brazilian, and embellished with a stylish volute carved into the back. Topping it off on the face of the headstock is the traditional C.F. Martin and Co. decal.
The paddle style headstock is equipped with vintage-style Waverly open back tuners and nickel butterbean knobs. In the past, I became very partial to Gotoh tuners and had them on three different Taylor guitars, two of which I “after-market” installed. The Gotoh high gear ratio tuners make precision tuning very easy. By comparison, I think the Waverly’s do an equivalently nice job and work well on my two Collings’s as well as the Authentic. They look very cool too!
The Neck
The 1937 D-28 was one of the earlier models that was built with fourteen frets between the body and the nut. Despite the fact that the guitar was at least 7 years old, the frets were in mint shape with no visible wear. Eschewing modern CNC milling, the neck is hand carved in the Martin custom shop to the shape of the original ’37 out of a mahogany block. This, in part, accounts for the high cost of this guitar.
I’ve got six total guitars made by National, Collings and this Martin. The necks all vary in shape and I happily play them all. The Authentic has a “1937” shape which is actually kind of meaningless to me; however, I will state it is a pleasure to play.
The 1 3/4 inch nut is bone and wide enough for comfortable fingerstyle playing. The fretboard is a solid black ebony which is somewhat difficult to acquire nowadays. Due to ebony wood scarcity and preservation, most fretboards of that material today have blond streaks randomly running through them. The fretboard inlaid markers are subtle but handsome 1937 diamond and square shapes.
The neck has a reinforced T-Bar to give it stability and it is attached to the body using C.F. Martin’s traditional dovetail joint. Unlike modern guitars (like my other 5), consistent with the design of that era, the Authentic has no adjustable truss rod. Since I tweak my guitar neck with the truss rod on occasion, I find this a bit unnerving; however, from everything I’ve read the Authentic’s neck is supposedly very stable. Right now the string to neck play is quite good up and down the neck. I imagine controlling the moisture content of this guitar is fairly critical to maintain neck stability!
The Body
The Authentic’s body is constructed with an Adirondack spruce soundboard and Madagascar rosewood back and sides. Every other acoustic guitar I’ve ever owned was built with a Sitka spruce soundboard, as is 80 percent of all other quality acoustic guitars. In the early years of the D-28’s construction all the tops was made with Adirondack (Red) Spruce; however, due to scarcity of the heavily logged Red Spruce trees, the guitar industry transitioned to the more plentiful Sitka Spruce. Sitka is a pretty tight grained wood that yields a warm response when played, whereas Adirondack, a wider grained wood, is harder and more glasslike as compared to Sitka, giving it a sharper more more immediate response. Adirondack is prized by Bluegrass flat pickers and strummers because of the way the top responds to those styles of play, but I think too that the boutique crowd also values Adirondack because it is a relatively rare, high status wood. I do not have the ear to detect the subtleties of Sitka vs Adirondack, but I do, very much, like the guitar’s overall tonality (for a very articulate discussion of the Authentic’s tone as it relates to Madagascar versus Brazilian back and side wood, I suggest you read this blog article).
The D-28 Authentic 1937 was first introduced at a 2013 NAMM show and records show that my instrument was ordered by Dave’s Guitar Shop for delivery to its previous owner in 2014. The initial production models of the ’37 did not utilize the Vintage Tone System (VTS), a torrefication heat treatment of the Adirondack soundboard to enhance the tone via “premature” aging. I think all subsequent production from 2015 on are torrified. I am agnostic about that type of wood treatment, but pleased the guitar has been played-in for 7-8 years in a natural manner. As I said before, it sounds quite lovely.
For a hefty monetary charge, C.F. Martin also offers an aging process in the custom shop to relic the instrument. I am not particularly enthusiastic about “relic” technique and am delighted this process was not applied to my Authentic. In fact, other than a barely visible crease-like ding in the soundboard, a small ding on the bottom, and some marking on the pickguard, this guitar was immaculate even though having been played for 7-8 years. The previous owner took great care of this guitar and makes me wonder if it ever left his home. Me, on the other hand, as much as I try to care of my guitars, I end up inadvertently beating the shit out of them because I play them and use them in and out of my home. Guitars are awkward shaped objects as they move through three dimensional space, and with me guiding them, they can attract wear marks, dings, and finish checking, so in the end I unwittingly relic them the old-fashioned way.
Unlike my Taylor 914ce, which was an exercise in excess, with abalone appointments galore, as well as wood bindings and purflings. The Authentic is more scaled down, but beautiful in its own right. You can see in the image to the left that the sound hole rosette is simple yet tasteful, and the soundboard is appointed with traditional bold herringbone purflings and grained ivoroid bindings. While I play fingerstyle and don’t generally like pickguards, if you are going to have one, the “old school” Delmar faux tortoise type is a nice one to have.
Rounding off the guitar’s top is the authentic ebony Style Belly bridge with long bone saddle. The bridge pins are polymer plastic with black dots. The bridge is located to give a comfortable 25.4 inch scale length.
A photo of the back of the guitar indicates the subtle beauty of Madagascar rosewood. The color of the wood is toward the red end of the spectrum and exhibits some nice but restrained grain. As suggested earlier, Madagascar rosewood has somewhat similar tonality when compared to the essentially unobtainable and certainly unaffordable Brazilian rosewood. A guitar constructed from Brazilian would be many times more expensive. Finally, note the 28 Style Zig-Zag (Authentic) purfling down the center of the back. It’s a very nice touch.
I love my guitars and I love to play them. It is a privilege to own and play National Resonators, as well as Collings electric and acoustic guitars, and now an exceptional Martin Authentic. Nevertheless, I view those guitars as tools and a means to an end, which is to make music. I won’t leave the guitars hiding in their cases preserved from the dings, scratches and bumps of use. They’re tools and I will hammer nails with them as long as I can.
To that end, I perform with my guitars around town, and host a monthly open mic night at a local coffee shop. I own a Genzler Pro Array and a Bose L-1 Pro 32 PA that I plug into when I perform. Consequently, I had a pick-up installed in the Authentic. In the image to the left you can see the jack for a K&K Pure Mini pick-up, an elegantly simple device that utilizes 3 transducers that are glued under the bridge plate. I’ve seen some high end guitar owners fret about adversely impacting the resale value of their guitars by altering them, such as adding a pick-up. I do not worry about such matters, especially with a low impact addition like the K&K.
Because the K&K Pure Mini is so simple, without onboard preamp and tone controls, I’ve built an acoustic guitar pedal board to manage the tone of the Authentic and my two other Collings. For more information about the board, click here.
Summary
The Martin D-28 Authentic 1937 is one of the “Kings” of acoustic guitars. It is made with incredible care and dedication to evoking the golden age of guitars. In my home the Authentic has fierce competition for playing time from a Collings 0002H, a Collings C10-35, and a National M-1 Tricone, yet at this time it rules the roost. It is a magical guitar and rules them all…
Example Sound Clips
Below please find some Vimeo clips I made with the D-28 Authentic. The clips were made on an iPhone 11 Pro Max with a Shure MV 88 clip-on Mic. The guitar was played through my pedalboard into a Genzler Pro Array acoustic amp. I added a dash of compression, delay and reverb. The clips was processed on a elderly MacBook Pro with iMovie. The guitars tone would probably be best appreciated with headphones.
The first two clips are the Authentic tuned in Open D:
