Rich tone should last as long as the inspiration
does. Martin SP Lifespan strings are the next level in studio
performance. Treated for long life, they repel dirt, grit and
other environmental elements that can quickly alter the sound of
your strings. The treatment is so incredibly thin, you won't even
know it's there. SP Lifespans are designed to last longer and
sound better so you can play on!
