Changing guitar strings is a relatively simple process; although it definitely requires some patience to correct them. Once you have completed the steps a few times, the process may take approximately fifteen minutes to complete. Important parts of the guitar that you will need to know: the bridge located under the soundhole, the neck of the guitar where the strings are made up of frets (this is most of the places you put your fingers while playing) and the head where you find the tuning pins (tuners). Here is a list of items you will need to have on hand: nylon or steel strings, wire cutters and tuner. There are six strings therefore six tuning pins located on the head. Each of the six strings runs from the bridge (at the base of the soundhole) along the neck to the correct tuning point. Inside the tuning pin there is a hole and the strings can be tensioned or (tuned) after the string has been passed through that hole. As you tighten the string you will notice that the hole will decrease in size and the tension will prevent the string from moving. At the end of each string is a sphere otherwise known as a ball end. Before we continue, please understand, depending on your acoustic guitar model, some guitars may have bridge pins and some may not. The guitar I will point to in my example does not have bridge pins. For guitar models that do this, these will also need to be removed. The purpose of the bridge pin is not only to hold the string in place but also to improve the sound. Therefore the bridge pin will be placed on the ball end of the guitar strings. Some more expensive models of acoustic guitars require these pins to be removed and sometimes replaced......center of paper......led do not cut off excess string until you have tuned the guitar and have all previous steps checked and performed correctly. If you cut the rope before double-checking everything, the rope may be too short if you need to repeat a step. Now, since the string has already been inserted into the tuning pin, you can begin tightening the pin using the wrench located on the right or left side of the tuning pin. The strings may start to move as you tighten them, so be sure to keep the ball end on the bridge of the guitar as you tighten each string. You can also place a finger on the string while it rests on the handle to maintain control. The tuning keys that are on the left side of the guitar or on the highest notes will turn clockwise while the tuning keys on the right side of the guitar or on the lowest notes will turn counterclockwise.
