Two weeks. That's how long they last. Two freaking weeks. I played 2 shows with them and a couple practices and now they're dead. They sound great when they're new, but terrible after 2 weeks. I guess they make them like that to maximize revenue? On top of that, I can't find the best strings ever anywhere now. Talking about Dean Markley Nickel Steels of course. So slinky and nickel steel users. What have you found that is better?
