Well if you're a guitarist, then it's easy - you can always record a second trackDominus wrote: If you're looking for a thicker guitar tone, you kinda need to double track it. Lots of people have tried to thicken up tracks with plugins and nothing really works all that well.
*Or*
I actually wire my guitars to record two tracks at a time. I install a stereo jack into the guitar, the neck humbucker is wired to the Ring, the bridge humbucker wired to the Tip. Then I use a stereo splitter cable to go into two inputs on my interface. Then I use different amp sims/settings on each track. I get a nice thick sound.
As for the other solution...I always thought that the whole point was to have 2 distinct tracks - I mean wouldn't 1 doubled track just sound louder, and that's it? The playing would be identical... Hmm..I'lll ask my guitarist
