Hello I have DR sunbeams on my p-bass now after having had lo-riders on for a while. I love both but suddenly the last couple of days the sunbeams seems to have become stiffer to the point that it is uncomfortable. The only thing I can think of has changed is that I have been using "GHS fast fret string cleaner and lubricant" on the strings and fretboard for maybe two weeks. I have just applied it after playing and followed the instructions on the bottle.. I wonder if anyone else has experienced this? This seems to have ruined the nice feel of the strings.. so do I have to put on a set of new strings or is it something that can be done to reverse what it has done to the strings.. wiping/cleaning etc.?
