Chris Rego teaches us how to change acoustic guitar strings in this tutorial. First, you will want to loosen up the strings and then remove them from the place they are at. After this, you will want to replace the strings and then wrap it three times around the post. Use the winder and insert it inside the key while you are replacing the new string inside. After this, continue to tighten the string depending on what you want the sound to come out as. Continue to do this for all of the strings on your guitar, then you will be ready to play all over again!
