I have just started learning the acoustic guitar. I have been and still am enjoying my new journey. I understand this is a never ending learning process. I very quickly discovered that on my fret hand the ringer finger is making it impossible to have the strings ring out cleanly. The problem....when I was younger the tip of the ring finger was removed due to an injury. Compared to the other fingers the ring finger tip is considerably fatter....to the point fretting a string is impossible without touching at least one other string. Any suggestions, tips, ideas, would be more than welcome......
