This is Tetragrammaton by The Mars Volta. 
I did not tab all of this myself,
my teacher figured out probably 75% of this.
kudos to him.

Enjoy

Use a loop pedal(recommended)

 do the chorus 4 times, but instead of ending on the hammer-on/pull-of part,
end it by hitting the 2nd fret on the a string, using an echo pedal and a whammy bar/pedal.

play this(with wah) while verse 2 is playing(loop it when your playing it in the beginning)

The next part is just a bunch of noise and samples from the song, and a guitar w/ delay 

continue playing the part before the breakdown(x4) 

play breakdown again and after that there is another section of noise and samples and then...

just speed pick this part /w dist and slight delay
the +'s just mean speed pick in this part
