Remove the old strings by rapidly unwinding the tuning pegs with your peg winder. Clip the twisty, unruly ends around the string post so the remainder of the string can be easily drawn out behind the bridge saddles. If your Fender guitar sports a rosewood fingerboard, now is a good time to rub a little lemon oil into it, making sure to keep the lemon oil off of the rest of the guitar.
Open your new pack of strings and locate the sixth, or low E string; start stringing at the top with the thickest string and work your way down. Insert the string through the back of the guitar body, out the bridge and up to the tuning peg staff. Pull the string tight through the tuning peg post, and locate a distance on the string about two and a half string post lengths beyond the post you are installing on now. Allow this extra length to slide back out so the string is slack; you will wind this extra two and a half length around the post.
Slowly wind the string with your peg winder with one hand while you keep the string feeding straight into the post with your other hand. The first and second strings may require routing through an additional saddle on the headstock. Tighten all strings until they sound and feel approximately in tune. Once all strings have been installed, tune them from the sixth low E to the first, high E. Play for a minute or two and then tune them again. You may have to repeat this step a few times until the new strings are properly stretched. After a day or two, trim the excess string length off the peg posts with your wire cutters.
