But before going into Riff 2 at 1:46, that first riff cuts off in the middle leading into Riff 
2. Like this.

Riff 2
Guitar 2 (1:47-2:25)
To me it sounds like the other guitar is just playing the chords,
but if you think that's wrong then by all means I encourage correction.

A|-4~~~~~~~~~~~~~~~~~~~~~~~~~~~4~~~~~~~~~~~~~~~~~~~~~~~~~--------------------| 
E|-3~~~~~~~~~~~~~~~~~~~~~~~~~~~2~~~~~~~~~~~~~~~~~~~~~~~~~--------------------| 

Riff 3 (2:26-3:03)
I won't do separate guitar parts because to me it sounds the same on both parts.
Again, if you hear something I'm not hearing then please leave a correction!
E|---------------------------------------------------------------------------|   
B|---------------------------------------------------------------------------|   
G|---------------------------------------------------------------------------|   
D|-2~~~~~~~--5---| just a simple A to C strum----------------------------------| 
A|-0~~~~~~~--3---------------------------------------------------------------|   
E|---------------------------------------------------------------------------|   

Riff 4 (3:04-4:18)
Fast strumming. At 3:40 there is clearly something going on in the background but it sounds 
synth-ey.
I can't quite make it out. If you can, leave an example!

(5:34-7:31)
Feedback and Synth going on here.
I won't tab it but to me it sounds like the progression of Riff 4, but super synth-ey.

(7:32-7:50)
Go back into Riff 2 HARD!!

Riff 6

Guitar 1
(7:51-8:08)
Immediately after Riff 2 and at 7:51, start this
E|---------------------------------------------------------------------------|

Guitar 2

and then it all comes full circle (8:37-8:47)

E|---------------------3~~~~~------------------------------------------------| 

the song blisters back into Riff 1 from (8:48-9:34).

Like Riff 1 going into Riff 2 at the beginning of the song, from (9:35-9:43),
it cuts off in the middle of both guitar parts before going into the final Riff
