Remove the ball end of the string at the headpiece end by lifting out of slot.

4. To re-string using single-ball strings...
To remove strings, turn tuning knob counterclockwise until the string ball is fully visible and can be removed. Do not loosen beyond this point. Remove the ball from the saddle jaw. Using the Hex wrench provided, loosen the corresponding Hex screw at the headpiece until you can pull string out of its slot.
To install strings, start by putting the ball end into the bridge tuner jaw. Keeping the ball in the jaw, insert the non-ball end through the corresponding headpiece slot and out the back of the headpiece.
Making sure that the ball-end is still in the jaw and that the string is aligned in the corresponding saddle, pull the string end tight as you tighten down the Hex screw. (Tighten Hex screw firmly but do not over tighten as it may damage Hex screw.) Tighten tuning knob and check for any string slippage. If slippage occurs, tighten headpiece Hex screw a little more. Cut used portion of string behind headpiece using wire cutters.
