The Big Muff Guitar
The Tools
A lot of people don't know that you can build a guitar with simple hand tools. Some tools you might find useful are:
an electric drill/driver
a hand saw
a soldering iron
a wire cutter
a wire stripper
pliers
sand paper
wood glue
wood clamps
a ruler
a pencil
a big pot of coffee
The Body
I drilled 4 holes in the top: two sound holes, a pickup hole, and a hole for the tone control. I also drilled a hole in the body for the instrument cable jack.
I drilled 4 holes in a little piece of wood and glued it to the back of the body. This is the tail piece where the strings will be anchored.
Electronics
You may decide not to use electronics in your guitar. I chose to wire up some spare parts I had lying around. A pickup can be any old single coil you find on eBay from a Strat or a Tele, you can get one for like 10 bucks. A 250K pot will run you about $5 on eBay or a guitar electronics store. Don't forget the capacitor on the tone control. Wiring diagrams can be found at this link:

The body is done!
The Neck
Guitar necks are commonly made from mahogany or maple, I made mine from a 3/4" thick by 1.5" wide by 15" long scrap of redwood. A very soft wood. Glue a piece of wood to the end to make an "L" shape and reinforce with a little triangle. Glue and clamp overnight to make a strong bond.
The headstock is made from a piece of redwood slightly wider than the neck, with holes drilled for the tuners, and with a 23 to 45 degree angle sawed at one end. I drilled a small hole in the neck and the headstock where they join and inserted a dowel for strength.
The neck and headstock are glued (no clamping required, let it dry overnight) and a little piece of wood is notched for each string and glued to the end of the neck.
Frets

Now mark with a pencil on the neck where each fret will go. I found the metric system more accurate in this instance.
Time for a small tangent in our article. A couple of years ago, my roommate's bicycle was mangled when it was sandwiched between a pickup truck and a V12 Mercedes-Benz. No one was hurt, but the bicycle was completely destroyed save for a single wheel. the bike was left injured in the front yard overnight and was promptly stolen! I hung on to this wheel for no reason in particular and now I'm going to cut up the spokes to use as frets on my guitar.
Use a saw to cut notches in the neck where the frets will go.
Cut the spokes with a heavy-duty wire cutter and glue them to the fretboard.
Come Together
I chose to bolt my neck to my body so that I can take the whole thing apart and replace pieces if I wish. You can also choose to run the neck through the entire body for superior tone!
Hmmm what to use for a bridge... a bent, rusty nail, perfect! Watch out for tetanus. Under the tail piece you see a little black wire that is connecting the strings to the back of the tone pot through a tiny hole in the body so that the guitar is grounded through you while you are playing it! Goodbye hum!
