Interesting reading....

There are some things that will work with any guitar to make them sound
better. All operations are easy to do and really worth the time.
1. If your guitar has a rear-routed tremolo cavity (eg. Stratocaster) that is
covered with a plastic cover and some screws, take it away. It´s amazing
how the overall sound of a guitar can change by simply taking away this
cover.
2. Take care of all screws on your guitar, they should be fasten VERY tight
and strong for a better sound. Critical locations are the screws for the
neck, the bridge and the tuners. Check them regularly.
3. If your guitar has a tremolo (eg. Stratocaster) and you don´t use it,
get it blocked with a piece of wood. This will increase sustain and
response drastically.
4. Shield your guitar (see corresponding project for this)
5. Let your guitar breath: for this you should take away the paint at any
location that can´t be seen, a critical location is the surface underneath
the bridge of a Tele or a Strat. Eric Johnson knows why he is doing that to
all of his guitars. You can also take away the complete paint of the inside
of the pickup cavities and the complete surface that is covered with the
pickguard.
6. Let your guitar breath: check the wiring of your guitar, you will often
find a lot of crappy cables in there. Get a high-quality cable and rewire the
complete electronics. It´s nearly unbelieveable what this can do to your
tone.
7. Let your guitar breath: check the routing for the neck on your guitar´s
body. Remove any paint, dirt etc. you find there and sand it until you
have an absolutely plain and clean surface. Do the same with the
corresponding location of the neck - sand away the paint and bolt on the
screws very tight.
8. Restring your guitar with pure-nickel strings and hear details you never
heard before from your guitar. Replace your cheap plastic nut with a good
bone nut to hear even more subtle details.
9. Change your cable with a very high quality cable (eg. George L´s) and
hear details you never heard before from your guitar.
10. Have fun :-)
