I was a huge fan of the original Martin Lifespan strings—they used Cleartone coating, which to my ears and fingers was as close as you could get to uncoated. Plus, they boasted the same durability and sparkle you got in uncoated Martins. So, to be honest, I was a little hesitant when Martin dumped Cleartone for their own in-house formulation. But that hesitation was totally unwarranted; in fact, I think the newest version of these strings is the best yet.
If you've been reluctant to give coated strings a go after years of playing regular uncoated strings, give these Martins a spin. You'll be surprised how much you like them. Then you can join our growing list of customers who will only play Martin Lifespans.
