Martin guitar stings are designed just as Martin guitars are - with performance, tone, playability, and top-shelf quality in mind. The Martin SP Lifespan strings are no exception. Treated with Martin's Cleartone proprietary formula, these strings last longer and repel dirt and oil.
Phosphor Bronze strings are bright, but slightly warmer sound than 80/20 bronze when first put on the guitar. They offer consistent tone over time. Phosphor bronze has a copper/tin alloy, making them sound brighter than regular bronze strings.
