Hold the guitar and place your thumb on the first fret to ensure the string stays in place.

Insert the guitar string winder into the the tuning peg.

Turn the guitar string winder clockwise to tighten the string.

The process of replacing strings A, G, and B is the same and you can follow steps 4 through 6.

Only tighten the string until it stays in place. If you tighten it too much the string might snap which may result in injury.
