These are the best guitar strings on the market. C.F Martin and co know exactly what they are doing when it comes to making guitars and guitar strings are no exception. Highly recommend these strings, they last longer (before sounding dull) and they sound fabulous

### ⭐⭐⭐⭐⭐ Great price, plus long lasting rich tone.
*by B***R on 22 October 2025*

The first set of these strings were a gift from a friend a couple of years ago. Prior to that I used “Elixer” strings . I welcomed the slightly heavier bottom , also they lasted ages . They produce a great tone and are terrific value for the money. I prefer the “Bronze” over the “Phosphor Bronze” , but that’s just my preference.
