Guitar strings tend to wear out over time. They lose their tone, lose their feel, become harder to keep in tune, and break more easily, so it's important to change out your strings if you want to keep sounding your best. Knowing how to change guitar strings is a vital part of being a guitarist. It really isn't a difficult task, but can be intimidating for new guitar players. With a little bit of practice and experience, though, you'll be replacing strings like a pro.
Tips: I strongly suggest that you change your strings at least every six months. For those who practice for hours every day, you may even need to change your strings every two months or so.
Step 1: Materials
New guitar strings (of course)
Pliers (needle-nose preferable)
Very soft and clean cloth (polishing cloth preferable)
String winder (I don't use one, but many people use them and they can speed up the replacement process)
Step 2: Parts of the Guitar
Step 3: Loosen and Remove Old String
You should begin with the low-e string, which is the thickest, and replace one string at a time. Some people like to remove all the strings at once and then put the new ones on afterward. I highly recommend NOT removing all the strings at once because it removes all the tension that the neck relies on and could possibly damage your guitar. Why risk it?
So start removing the low-e string by unwinding the tuning peg - you should be turning the peg toward the body of the guitar - until there is enough slack so that you can easily pull the string out of the hole of the peg.
Tip: This is where that string winder would come in handy to speed up the process.
WARNING: Do NOT attempt to remove the bridge pin before loosening the tension on the string. It could harm you or your guitar, and nobody wants that.
Once you have done that, use your pliers to pull the bridge pin for that string out of the bridge.
Tip: Don't be too rough with your pliers if you don't want your bridge pins to look terrible. It is easy to dent, scratch, or break a bridge pin if you aren't careful.
Once the bridge pin is out, simply remove the ball end of the string from the hole. You can discard the old string or keep it if you wish; there is no need for it for the rest of the replacement process.
Step 4: Clean Your Guitar
Step 5: Securing the New String in the Bridge
Now, as you slide the bridge pin back into place, make sure to align the notch in the bridge pin with the string and pull the string up lightly so that the ball slips snugly into place. You should feel the ball "secure" itself in place. The ball should rest just beneath the head of the bridge pin, not beneath the tip of the bridge pin.
Once you think you've secured the ball end of the string, push the bridge pin back into place and give the string a little tug. If the bridge pin comes loose or pops out, the ball end of the string was not secured correctly. If it stays tightly in place, move on to the next step.
Step 6: Winding the New String
Turn your tuning peg until the hole points perpendicular to the neck of the guitar (as seen in image 1).
Now pull the string toward the headstock so that the majority of the slack is gone. At about one and a half inches past the peg you will be feeding the string through, crimp the string at a 90 degree angle so that the string points away from the guitar (see image 2).
Feed the string through the hole until it is stopped by its bend (see image 3) - this should create a good amount of slack. Once you've fed it through as far as you can without forcing the crimp through, crimp the string again so that it points toward the top of the headstock (see image 4).
As you begin to turn the tuning peg away from the body of the guitar, tightening the string, you will need to create tension by pressing the string down with your pointer finger and pulling up and back on the string with your thumb and middle finger (see image 5). Make sure the string lies in its notch in the nut. This makes winding the string significantly easier and smoother. If you do not do this, the string will simply unravel while you try to tighten it.
Ok, as you turn the tuning peg, make sure that the wrapped string passes over the end of the string protruding from the hole in the tuning peg (see image 6). This is only done on the first wrap around.
On the next wrap around, and each following wrap around, make sure that the wrapped string passes under the end of the string. You may need to physically move the string to ensure that it passes under the string end (see image 7). Every wrap after that should pass below the wrap before it (see image 8). You should avoid crossing the strings or letting them overlap. Continue tightening the string until the string is close to being in tune.
Step 7: Stretching and Tuning the String
Simply grab the the string at about the twelfth fret and pull upwards for about six seconds and then again over the sound hole, toward the bridge. It's okay to give it a good stretch, but don't overdo it. You don't want to pop a brand new string! The pitch should be noticeably lower, so re-tune the string. Repeat this process until the pitch doesn't drop significantly. It shouldn't take more than four or five stretches.

WARNING: Be especially wary when stretching out the lighter strings. The high-e string can be surprisingly easy to pop.
Step 8: Trim the Excess String
Congratulations, you've just successfully changed your guitar string!
Step 9: Repeat
Tip: Be aware that once you start replacing the highest three strings, the direction you turn the tuning pegs will be reversed, as will the direction in which you feed the string through the hole in the peg. Just remember, you should always turn the peg toward the body of the guitar to loosen and away from the body of the guitar to tighten, and the string should always point away from the headstock when you feed it through the peg.
And then you're done! Hopefully the process got easier as you went along, and I hope that this instructable was helpful for you. Happy playing!
