I've been playing my freltess for a little over a year now. I usually play an hour a day, I do lots of slides (Mick Karn's basslines). Around two months ago I changed stock roundwounds for Ernie Ball Hybrid Slinky, because they felt really worn even I gave them a good clean. They felt great but few weeks after breaking those in they already started feeling really sticky and extremely unpleasent to play. I cleaned them but it didn't help at all. It feels as if they're about to cut through my fingers. Is that possible they're already dead?
