Difficulty: Moderately Easy
Step1
Lay the guitar on a flat surface and start with the E string (the thickest one) or the broken or worn string. Continue unwinding until the string almost falls off.
Step2
Uncoil the string from around the tuning peg and remove the end of the string from the small hole inside the peg. Remove the other end of the string from the bridge by pulling on the bridge pin. If it's difficult to remove, use a set of pliers to wiggle it.
Step3
Place the end of the new E string with the ball into the hole on the bridge, and slide the bridge pin back in place. Pull the guitar string with a slight amount of pressure until the ball snaps in place.
Step4
Bring the string to the neck, drawing it up about an inch over the tuning peg. Bend the top in toward the tuning peg and feed it through the hole in the peg.
Step5
Wrap the string around the tuning peg counterclockwise until the string is about as tight as the remaining strings on the guitar.
Step6
Tune the guitar string and cut the excess wire with wire cutters, but don't cut the wire too close. Leave a little extra on the end of the string so the guitar has a deep tone and tuck it under the tuning peg.
