Most control problems start quietly. One day, the guitar feels normal, and the next day, you’re fretting hand works harder for the same chord shapes. Notes that used to land clean begin to smear, and bends return a little sharp or flat. Players often blame their hands, then change strings, picks, or posture, yet the friction stays. In many cases, the instrument has drifted, and small wear points are no longer behaving the way your technique expects.
