I haven't seen this discussed so thought I would ask. I've been playing almost a year now and callouses are nice and tough. And like most of us, I get grooves in my fingertips when I play.
My problem is that sometimes, but not all the time, as I finger a chord, my fingertip will land on the edge of the groove, then slip into the groove making a harsh clang. The other thing that happens, mostly on the ring finger and pinky, is as I change chords, the groove will 'grab' the string, making an unintended pull-off.
Any suggestions? I will buff them before I start, but then a new groove will evolve.
