C. F. Martin & Co. has been Inspiring Musicians Worldwide for nearly two centuries with their superior guitar and string products. Martin guitars and strings remain the choice for musicians around the world for their unrivaled quality, craftsmanship, and tone. Throughout the companys long history, Martin products can be seen and heard across all genres of music and in all segments of pop culture, from concert and theater stages to television and movies.


With an unwavering commitment to environmental sustainability and responsible manufacturing practices, Martin continually drives the acoustic guitar market forward, introducing innovative features that have become standards across the industry. These groundbreaking innovations include the introduction of X-bracing, the 14-fret guitar, and the Dreadnought size guitar.

Geartree greatly values the rich relationship we have had with Martin Guitars for many years. Martin Guitars stand on their own in terms of quality, tone, sustainability, and innovation. When customers ask what guitar will give them the best sound at an affordable price, we introduce them to Martin Guitars.


Martin has also led innovations in strings, such as introducing the first high-tensile strength steel-string core wire; the first nickel acoustic strings (Martin Retro); the proprietary Titanium Core strings; and now the groundbreaking, new Authentic Acoustic line, which offers unmatched stability, tone, comfort, and longevity.

 Questions & Tips

Q: I can't find my truss rod, what should I do?

We recommend that your guitar be taken to an authorized Martin service center to have adjustments made. Incorrect adjustments may cause damage and may affect your limited lifetime warranty.

Q: What type of strings came on my Martin guitar?

From time to time we changed the type of strings used on new Martin guitars. 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.

Q: How often should I change my strings?

Strings usually require changing every few weeks depending upon playing 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.

Q: Where can I find the serial number on my guitar?

A Martin Guitar will have the model designation and the serial number etched on the neck block. Look in the soundhole toward the neck to see where this is etched.

Q: Where are Martin guitars made?

Martin guitars are made in Nazareth, Pennsylvania with the exception of the X Series, Backpacker Series, Road Series, Dreadnought Junior, PA5 models, and select ukuleles which are made in our plant in Mexico.

Q: What is HPL?

HPL stands for high pressure laminate. It is a composite material made from paper and resin that is pressed at very high pressure. The surface will have a wood pattern (Mahogany, rosewood, Koa, etc.) and a protective clear coating. It is not a wood veneer.

Q: What is Black Richlite?

Black Richlite is a composite material that is made from paper and resin pressed at high pressure.

Q: How do I clean or polish my guitar?

To clean your guitar, wipe it down with a clean, damp cotton cloth with water then a dry cotton cloth to dry. For polishing, we recommend using Martin Polish and Cleaner which is available for purchase online and in our 1833 Shop. We recommend this polish for gloss finish guitars but not satin finish. It will not harm satin finish guitars, though after time the finish may begin to shine unevenly. It is best to use just plain water on satin finish guitars.
