Have been playing guitar for many years now and from that experience can't say I was all that impressed with this set of strings. Did not maintain intonation as expected and definitely a weak string. Don't expect several of them to hold up for very long... and I change strings fairly regular due to the amount of playing I do.... but, these didn't withstand the usual period. Mostly disappointed with intonation. Prefer D'Addario hands down. With D'Addario I get great intonation and much better longevity, even beyond my typical switch outs.
