Last week I was due for a string change. Been using GHS Med-Lt phos bronze (Bobby Osbournes) with pretty good results. The only PBs I happened to have was a set of J74s so I used them. At first the mando was dead, unresponsive. It got a little better but not much. I told myself to give it a week. Well that was today and I was only too happy to cut those strings off. Had a spare set of GHS Silk and Steels lying around and thought I'd try them out. WOW, let me repeat, WOW! My mando responds very well to them. It's alive again. After an hour and a half of noodlin' around it's louder, sweeter, deeper and more responsive to touch. My new favorite strings. I've heard the horror stories on their short life span so I guess I better order some more!
Just thought I'd pass along my success story for anyone else in the same prediciment.
All the best,
