I was playing a gig last night (which I haven't done in quite awhile), and since I started playing again I have switched to flatwounds. I noticed as the night wore on that the strings where I was plucking with my fingers seemed to get very sticky. I tried wiping it down, wiping my fingers, washing with water, etc., but it didn't seem to help. Maybe the skin on my fingers was just getting chewed up some, I don't know. Would something like Fast Fret or FingerEase work with flatwounds? Any other suggestions?
