1Notice if you have a floating bridge, jam it with something. To do this, bend the bridge up (like you're doing a dive on the guitar) and put something between the guitar body and bridge. Your tremolo bar will work for this, but a ruler is best.

2Loosen the strings by down-tuning. Once they're loose enough to touch the fret board, cut or pull the strings out of the pegs.

3Go on a floating bridge and pull the strings out of the back of the bridge. On a regular bridge (like a Fender Strat or any other string-through guitar) just pull the strings out of the back of the guitar's body. If you have a wrap-around bridge, you will be able to pull them out of the underside of the bridge.

4Replace the strings. Just slide them in where you removed them.

5Put the strings through the pegs on the head of the guitar. Here's the best way to do it: Push the strings in until they're about as loose as I described in step 2. Now, bend the string in the OPPOSITE direction you'll be turning the pegs for higher tuning. Wind the string around peg in a neat helical coil for smoother tuning. Put the thinner strings twice through the peg hole to reduce string slip.

6Twist the pegs until the string is on correctly.As the string comes around push the front under the string to have it lock. Try putting some tension on the string (by pulling it up) at about the 12th fret. Pull it up firmly, but don't snap the string. This keeps the string wound tight around the peg, not just wound loosely around, which may not work at all.

7Remember that Once all the strings are on, tune them! Do this by removing whatever was holding up your bridge (if you had a floating bridge, that is) and slowly let the bridge down. Not extremely slowly, just move it down so the strings don't snap. To tune, you just pluck a string and tune it like you would before playing. Make sure you're not tuned too low or too high! Do this by playing some chords or something, and see if it sounds right. Now just tune all 6 strings, and you're done.

8Make sure your guitar is working properly, crank up your amplifier and play a power chord in pride. You've just changed your strings.
