Its true, and im proud of it. Played for 18 years, They will very very rarely fail. Ive never had tuning stability issues on hardtail guitars since i learned from an early age to apply the strings correctly to the guitar in a tense way. As a matter of fact, i most often change the strings cause i use them so long it feels like they get old, i broke a string last week - first broken string in about 4 years. I change them every 3-6 months i believe, on all guitars. If this doesnt testify how well they last, i dont know what will. Im into classic rock and 80s metal and im not gently to my guitars, i do not own a whammy bar guitar though. These strings are a great choice, but you probably already know Ernie Ball, if not. You've got to.
