Double tracking guitars is the process of recording your guitar part on one track and playing the exact same part on another track. There are a few variations of this.

COPY / PASTE METHOD
Record your first part on track (A). Then Copy / Paste (A) on to a new track (B). Now you have the identical part on 2 tracks. You will hear a boost in volume but once you export your track, it will sound the same as a single track so you have to take it a step further. Next you want to pan them apart so you don't have 2 guitars on top of each other. Imagine a stack of coins, you can only see the top coin but you know there are more. Now if you were to spread them out in front of you, you'd see more clearly what amount you had. Same with panning your guitars. For example, if you pan (A) to the left and (B) to the right all of a sudden you will hear 2 guitars covering more "ear space." There are several degrees. "0" which is center and "-64" is far left or "+64" is far right. Before you hear this difference you have to offset your tracks.
To offset take track (B) and move it slightly along your track line. It is best to do this with magnification or zooming in on the tracks. (refer to your software manual and you will find a zoom option) Once you have zoomed in on your tracks, you can click-hold one track (B) and move it so that it is not perfectly in line with (A). This will create even more "ear space" and make your guitars sound more full, and increase the stereo effect. Let your ear be your guide. If it doesn't sound right, move it a bit more, or less.
TROUBLESHOOTING
You may experience your track automatically jumping to a specific point, rather than the small increment you want. This is called SNAPPING. Your program will allow you to turn this on or off. In Garage Band, under the Control menu, it is simply called "Snap to Grid." In Cubase you will find a button at the top, when lit, snapping is on. (pictured below)
The benefits of Snapping is to line things up directly to a bar or beat but when you are doing slight movements. Turn it off.
PLAY IT TWICE
Randy Rhoads often played his tracks 2,3 or 4 times to get a huge guitar sound. Some love it, others...not so much. I loved his playing but I am personally not fond of the recording method. He had the talent to nail it each time. If you don't it will sound sloppy so you have to really know your part. For this method simply record track (A), then record your part again on track (B). You could offset them as above but often your playing won't be spot on so the offset may not be necessary.
TROUBLESHOOTING
If your tracks still sound thin you may want to try:
- Changing the sound of (B) so it sounds like 2 guitar players. Even switching pickups may do the trick.
- Don't play the part exact. If you loosen up (B) you end up filling more "ear space." This requires a bit of pre-practice unless you are a good improv musician.
- Try using a different guitar, if you did a track (A) with electric, use acoustic for (B). If you do this you may want to loosen up the track as mentioned above.
- By "loosen" I mean play counter rhythms, A different, but complimenting strumming pattern.
I prefer recording 2 different parts. I find that it fills the space so much better but when you have a heavy riff that begs to be huge, double it or copy/paste/offset.
