How To Change Guitar Strings
A Word About String Gauges
Strings come in variety of gauges. The gauge of the string
tells you the thickness of the strings. The lower the
gauge the thinner the strings, higher gauges mean thicker
strings. Most manufactures display the gauge size by the
size (diameter) of the high E string (the smallest string).
Typical gauges run from .008 to .0012.
Different strings are made for electric guitar and acoustic
guitar. The most popular electric guitar gauge is .009.
Most acoustic guitar players use .010. Novice and intermediate
level guitarists will want to stick with these common
gauges.
More experienced guitarists may want to experiment with
higher gauges (.011 or .012 and up) because they offer
better sustain and tone. Higher gauged strings are harder
to play. They feel "heavy" under your fingers
and take some getting used to. They'll also make your
fingertips quite tender if you're not used to them.
Do not use heavy gauge strings until you have had a guitar
technician look at your guitar. Using heavy gauge strings
may require adjustments that only a qualified technician
should perform.

Changing Guitar Strings
There are thousands of types of guitars and many of them
need different methods of changing strings. Use this guide
as just an example.
One thing that will help you wind and unwind your strings
faster is a little device you'll find at your music shop:

Take you string winder (or if you don't have one, do
it by hand) and unwind the top string until it comes off
the tuning machine. Trash the old string.

Insert your new string through the bridge or the bottom
of the guitar tremelo system:

Pull the string out on the other side:

Insert the string into the tuning machine:

Make sure you line the string up into the nut:

Now take your string winder and wind it up:

Hold the string with your extra hand as below to keep
slack out of the string:

Wind the string up until it doesn't rattle against the
neck, then clip the access string poking out of the tuning
machine:

Repeat this procedure for the other 5 strings.
