I just bought a new set of diaddario's and expected a great set of strings with good life in them. They sound pretty good but, within a couple of days I could hear and feel them going. In a couple of weeks they just sounded dull. I paid about 50$ at the shop and a set of Ernie Balls was just 40$. I have had Ernie Balls and I think they are far superior to Diaddario's. I will never waste my money on them again. Have any of you have a bad experience like this with Diaddario's?.
