The Martin SP Lifespan 80/20 bronze 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.
What started as a simple string and pedal sales catalog has grown exponentially over the past thirty years. The early days were a time where catalogs didn't have much of a presence in the industry, but what began as a college dorm room operation grew rapidly. In 1986 we moved to a full product offering and 64-page catalog, which over the years has grown to 162 pages. Join the AMS family and get your free catalog now!
