Old guitar strings may break or lose their tone and become harder to keep in tune. You might feel comfortable at first having a teacher or someone at a music store change your strings for you, but eventually you will need to know how to do it yourself. Changing the strings on a guitar is not as difficult as it may seem and the best way to learn how to do this is by practicing. Guitar strings are fairly inexpensive and you may have to go through a few to get it right the first time you try to restring your guitar. How often you change your strings depends entirely on how much you play your guitar, but if the same strings have been on it for months, it’s probably time for a new set.
Most strings attach at the headstock in the same way, however electric and acoustic guitars vary in the way in which the string is attached at the bridge. Before removing the old string from the guitar, examine the way it is attached to the guitar and try to duplicate that with the new string. Acoustic guitars usually use removable bridge pins that fasten the end of the string to the guitar by pushing it into the bridge and securing it there.
Follow the series of photos below for a basic description of how to change a string. Before trying it yourself, read through the quick tips for beginners on the following page.
Use a string winder to loosen the string.
Remove the old string from the tuning post.
For each string, carefully lift the bridge pin and remove the string from the guitar. Set the pin aside and discard the string.
Remove the new string from the packaging and uncoil it.
Thread the end of the new string over the nut and place the end of the string in the groove on the bridge pin. Carefully push the pin back into the bridge to lock the string in place.
Pull the string along the neck and thread it through the small hole on the tuning post.
Hold the string in place just after the nut with your finger and tighten up the slack in the string with the machine head.
Carefully tighten the string and tune it to the proper pitch.
You can cut the old string off the guitar but you may want to unwind it instead and save it as a spare in case you break a string later.
Check to make sure you have the correct string in your hand before putting it on the guitar. The strings may be color coded at the end to help you identify them.
Be sure to wind the string around the tuning post in the proper direction (see photos), and leave enough slack to wind the string around the post several times. The string should wind around the post underneath itself to form a nice, neat coil.
Once the extra slack is taken up and the string is taught, tune it very gradually to pitch, being careful not to over tighten and accidentally break the new string.
Once the string is on the guitar and tightened up, you can cut the excess string sticking out from the tuning post with a wire cutter. The sharp tail end that is left can be bent downward with the wire cutter to get it out of the way and avoid cutting or stabbing your finger on it.
Check the ends of the string to make sure it is sitting correctly on the proper saddle and space on the nut.
New strings will go out of tune very quickly until they are broken in. You can gently massage the new string with your thumbs and fingers once it’s on the guitar, slightly stretching the string out and helping to break it in. Then re-tune the string and repeat this process a few times for each string.
