You can look up the manufacturing date of your guitar by serial number here. If your guitar does not have a serial number and was manufactured prior to 1898, it may only be identifiable by measurements, appointments and stampings. If that is the case, you can send photos and a description of the instrument below.

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.

You can submit your registration online, or by mailing in the warranty registration application included with your guitar.
