How can I fix a guitar string that has broken?

To fix a broken guitar string, you will need to replace it with a new one of the same gauge. First, remove the broken string by loosening the tuning peg and unwinding it. Then, insert the new string through the bridge and the tuning peg, and tighten it by turning the tuning peg until the string is in tune. Cut off any excess string and tune the string to the correct pitch.
