The truss rod is located inside the soundhole. Look toward the neck to see the access hole. The one-way adjustable truss rod was implemented in 1985. The two-way truss rod was implemented in 2006. The two-way truss rod is recessed further than the one-way rod and you will not see it. We recommend that your guitar be taken to an authorized Martin service center to have any adjustments made. Incorrect adjustments may cause damage and may affect your limited lifetime warranty. We do carry truss rod wrenches––depending on which Martin you have, the wrench will be either 4mm or 5mm.

The Shenandoah series guitars were considered a mid-range model priced between the Sigma series and higher end Martins. Available from 1983 – 1993, they were assembled in Nazareth, Pennsylvania from imported parts. Shenandoah series guitars included tortoise-style pickguards and the Martin Thinline pickup as standard features. The models included a lacquer finish with tops made of solid spruce, necks made of mahogany, and the fingerboards and bridges made of rosewood. The back and sides were made from laminates, rosewood, mahogany, or maple. The Shenandoah’s came with the limited lifetime warranty to the original, registered owner. You can determine the year your Shenandoah was manufactured by its serial number.

Mineral deposits will show as tiny white flecks and are considered a normal characteristic of wood. They form as the tree extracts nutrients from the soil. During the finishing process these deposits may appear lighter in appearance. Mineral deposits will not affect the tone or structural integrity of the wood.
Brazilian rosewood is considered nearly extinct and as such is extremely difficult to obtain. It is available in very limited quantities for special limited edition models. Additionally, all rosewood models prior to 1969 were made with Brazilian rosewood, aligning Martin’s reputation for superior tone closely with the use of this wood. With our remaining inventory of Brazilian Rosewood diminishing and extremely rare, it is our commitment to utilize the material responsibly, as Martin Guitar presents this exceptional opportunity to our customers.
In an effort to attract industry to Brazil in the 1960s, Brazil placed an embargo on Brazilian rosewood logs. In addition to the embargo, Brazilian rosewood logs that were large enough to create two-piece Dreadnought back was quickly becoming depleted. In response, Martin Guitar began using East Indian rosewood from India. Martin Guitar ceased using Brazilian rosewood in standard production for complete sets of back and sides in 1969.
Martin Guitar’s basic model designation system begins with a letter or 0 which denotes the body size including 0, 00, 000, 0000, Jumbo, D, , and Grand Jumbo. The following number designates the appointment level. For example, the 15 series includes mahogany, no bindings, and a satin finish. 16, 18, and 28 represent the upgrade to rosewood back and sides. H designates herringbone and scalloped braces. 35, 40, 41, 42 and 45 add represent the addition of pearl. 50 and 100 include highly decorative inlay. The number also indicated the price of the instrument. E indicates the model is an acoustic electric.

Strings Care
We are currently stringing most new Martin guitars with Martin SP Lifespan acoustic guitars strings. Martin SP Lifespan strings use an exclusive high-tensile strength core wire to better hold tunings and resist breaking; all six strings are treated with our proprietary treatment to enhance the life of the string. In general, all non-cutaway dreadnoughts and jumbo guitars get medium gauge strings. Most X-series, cutaways, and smaller models such as the OOO and the OO get light gauge strings. Most 12 string guitars get extra light gauge. Guitars designed for nylon strings will be strung with our Martin Classic strings. For the most current information of what type of strings came on your Martin, please refer to the model specifications for your guitar.
Tension varies by gauge and guitar style. However, we include general tension information based on a 25.4" scale length on each string product page.
Many of the traditional metals used in acoustic strings are subject to the corrosive effects of oxygen and moisture. Body chemistry can influence the longevity of a string as well; if a player has high acid content in his/her perspiration, strings may tarnish more quickly as well. We recommend always washing hands before playing, wiping down the strings when done, and storing the guitar in its case to increase the longevity of the strings.
Yes, it is safe. All of our six string guitars designed for steel strings have been tested to withstand the tension of a medium gauge string. However, since each top is unique, take note if the top starts to rise abnormally. If this happens, go back to the lighter gauge strings.
Your string breakage problem may not be the result of the strings you are using. Strings often break due to an excessively sharp break angle or rough area at the saddle, a rough area at the nut, or due to restringing method around the tuning machine post. Analyze the frequency you break strings and the location of the break, and then discuss with an authorized Martin Warranty Repair Center. If you are a heavy strummer, a medium gauge string may be preferable.
You can switch easily between types of wrap material, or types of strings - Marquis, SP, SP Flexible Core, etc. If you are changing more than one step in string gauge we recommend that you have the first change done professionally to ensure the set up remains comfortable, intonation accurate, and tone correct. For example, you if normally play lights you should be able to change to a custom light or medium light without issues. However a jump from light to medium or to extra light could affect playability or intonation.
Strings usually require changing every few weeks depending upon playing frequency/style, desired sound and environmental conditions. As a general rule, when strings require re-tuning often, it is time to change the strings. Changing strings provides a great opportunity to clean and service the guitar, including cleaning and dressing the fret board, polishing or cleaning the top and body, checking the nut and saddle for issues, and possibly changing the battery on a pre-amp if mounted inside the sound hole.
String changing does not have to be complicated. Watch how to change strings on your guitar in our video Restringing Your Acoustic Guitar.
Choosing Strings
We still make our own strings as we believe strings are important to the sound of the instrument. We put the same care and craftsmanship into the design, sourcing, and manufacturing of the strings as we do our instruments. We set the highest industry standards of quality and design for our SP core wire. All of the metals are sourced to our specifications. We design and build our own string winding equipment The strings pass a rigorous testing each day at the Martin factory.
92/8 Phosphor bronze strings have a higher composition of copper blended into the metal than 80/20 bronze. Generally 80/20 bronze starts out with a bright attack and will mellow quickly while phosphor bronze maintains a warmer more consistent tone and with greater complexity. We generally string Martin instruments with 92/8 phosphor bronze strings, however some models will ship with alternate Martin strings.
Traditional wound acoustic strings are based on a hex –shaped core wire with a single wrap of metal. We start with a round core wire and wrap it first with a soft material. We then wrap the modified core with the silver-plated copper (silk & steel) or 92/8 phosphor bronze (Silk & Phosphor). This process provides a subtle softness to the tone and creates a pleasant-feeling string under the finger. These strings are commonly used in folk and singer/songwriter genres.
We offer a broad selection of gauges and string types so you can find the best string for your style of play, instrument, and desired tone. In general, lighter gauge strings put less pressure on the instrument top and will produce a lighter softer sound as well as reduce finger fatigue. Light gauges are often chosen by fingerstyle players and singer/songwriters. Heavier gauge strings will drive more energy to the top and therefore create more complex and louder sounds. Bluegrass, rock, and blues players tend to use heavier gauge strings. Our Flexible Core strings use a unique construction method to reduce finger fatigue, increase strings response, and maintain equivalent tension on the top as standard sets. Flexible Core strings are played by masters like Tommy Emmanuel yet are highly recommended for beginners.
We created our Marquis line to pamper your guitar by adding a soft wrap to the area near the ball-ends. This protective layer helps to prevent wear and tear on the bridge and end plate as you play. The added soft layer can also help seat loose bridge pins. Marquis strings put a comforting layer of protection in place every time you change your strings.
Yes. We have designed our strings such that they will fit on most brands and styles of instruments.
