I know lots of people like these strings, which was the reason for me to try them, but for me they totally did not work. It may be because I have an old guitar (a 1947 Gibson J45), but the strings sounded dull and were bereft of character. My guitar, which normally has a very distinct personality, turned into an anonymous non-entity. The strings clearly are well made, and there was no notable degradation in tone in the two weeks I had them on my guitar, but I'll not be using them again.
