Just few hours ago i broke my G string while doing some heavy slapping. Then i noticed while playing the other strings , it makes a buzzing sound and i also noticed that my action is extremely low. My action is suppose to be medium. Did my neck relief screw up when the G string broke. Do i need to do something with my truss rod. I am sure I do because the actions is incredibly low. By the way i have a cort curbow 4 string and i think you use a phiilip screwdriver to adjust the truss rod. But i not going to touch it for now.
