Repairs

If a particular string does not sustain the pitch, the tuning peg is probably too loose. It can be adjusted by tightening the small screw on the back of the head knob. However, tightening the screw too tightly may damage the knob. If you loosen the screw in the middle of the knob, the peg can be completely removed and replaced with a new one.
