Hey all, I dont know whats going on, I have been playing for close to ten years, and all of a sudden I have gotten really bad blisters on my index and middle plucking fingers the last two shows I have played. I think it might be my strings, but not sure. I used to play Blue Steel strings all the time, then switched to some Wooten strings. I now switched back to Blue Steel and think these may be causing the problem. Anyone else experience this after years of playing?
