There's a few artistic liberties in this tab.
To make the guitar sound fatter, I've tabbed this on a 
7-string, tuned to ADGCFAd (Drop down 1 whole note)
There is no real info on what/how this is player [with], 
but it seems to be rooted in an A. Now, as an A on a 
standard tuned guitar sounds to thin for this kind of 
track, I decided to go with the 7-string and drop the 
tuning.

Several tracks use octaves (where there might not 
supposed to be), again to fatten the sound (this 
includes some bass, vocals, synthsound)

The 'Dubstep'-part of the guitar-section is, well, 
extremely difficult to even get close to in midi-format, 
so it's more of a "you-might-get-close-if-you-play-it-
this-way-on-your-guitar"-style-tabbing.

You are going to need a Digitech Whammy in order to 
even come close to the sound on this track.
If you want to do it even better, try getting a Kaoss Pad, 
or a Manson Kaoss-type guitar ($$$).
You're sound also need to be heavily fuzz-infused, 
regular distortion/overdrive won't cut it, as it's too 
clean, not enough noise.

tl;dr;
Don't bash me because the guitar sounds f...ed up, it's 
more effects than notes (midi only does notes), try 
instead to listen to all the other stuff, that's pretty neat ;)
