Changing your guitar strings can sometimes be an off-putting or laborious chore, though it is one that has to be done in order to properly maintain your instrument. The Martin Lifespan range of acoustic guitar strings are designed with new, patented technology to ensure they stand the test of time but also provide you with an excellent, balanced tone.


For nearly two centuries, Martin have been crafting some of the finest guitars we have ever seen or heard. This family-owned company are continuing to do this in their own way while trying out new and innovative techniques that make their products (be it guitars or accessories) stand out from the rest. Over the years, Martin guitars have been the instrument of choice for a huge range of different guitarists, from Johnny Cash to the one and only Elvis Presley among many others.


The Martin Lifespan Phosphor Bronze Acoustic Guitar Strings are a medium gauge which may be favoured by those who own a dreadnought or jumbo style acoustic. Medium gauge acoustic strings are also great for a playing style which combines fingerpicking and strumming. These strings have been given an innovative and new patented treatment known as Cleartone technology which combines the ability for the strings to last longer but vibrate as naturally as possible. Though you will hear the difference, it won’t affect how your strings feel on your fingers, so you’ll barely notice the treatment and you will be able to play extended periods of time. The strings are also protected against corrosion and dirt, and they are durable enough to resist against deterioration.


The Lifespan medium gauge strings produce enhanced rich bass notes with crisp trebles, with a generally warmer, darker acoustic timbre. The phosphor material in the strings allows them to retain this tone for longer durations, making them live up to their “lifespan” name. If you’re the kind of guitarist who would rather put off changing your strings until absolutely necessary, the Lifespan strings are perfect for you, and will certainly last a long time.
