Hi String Breakers, I want to know something about CAPO. 1. What is a CAPO? 2. What is the logic behind using a CAPO? 3. What happens when I keep the CAPO in first fret or then move to 2nd fret and so on... 4. Should CAPO be used? 5. Which Brand of CAPO and its cost? If you have any other points which I have not asked please tell. Happy String Breaking , Sourabh.
