Many players delay changing strings. We put up with dead strings to avoid the task. Coatings that extend the life of the string may change the tone and feel of the string to the point of making it a compromise - long life or natural tone.
We believe that string vibration should be natural and unrestrained for the cleanest and liveliest tone. Martin's search for longer life strings led them to Cleartone. Some methods of coating a string tend to dampen the vibration of a string and degrade the natural tone.
The Cleartone proprietary treatment creates a barrier to dirt and grime yet the treatment keeps the windings open to deliver a natural brilliant tone. Superior Performance meets Long Life!
The all-new Martin SP Lifespan acoustic guitar strings are treated with Cleartone proprietary technology to bring you the longest possible string life without sacrificing tone or natural feel.
Martin SP Lifespan strings are designed to repel the oils and dirt that can deaden strings. All six strings are treated to preserve the natural Martin SP sound and feel that players prefer.
