I tried as best I could on this one. I may go back and
revise it later. You're welcome to do the same.

The main riff is kind of in two parts.
Variations of the second part are used for the verse.

   'part 1'-
   E--------------------------------------|
   B--------------------------------------|
   G--------------------------------------|
   D------------------2--(2)--5--4--2-----|
   A------------------2--(2)--5--4--2-----|
   E--0-2h3--p0---h7--0--(0)--3--2--0-----|

   'part 2'-
   E------------------------------------|
   B----------------2--(2)--------2-----|
   G----------------2--(2)--5--4--2-----|
   D----------------2--(2)--5--4--2-----|
   A--0-2-3p0---h7--0--(0)--3--2--------|
   E------------------------------------|

Some of the variations that I hear are variations in pull-offs
(these occur throughout,I think) and the extra chords that
I have indicated with parentheses.

The next big riff goes like this:
                               I forgot my name...
   E--------------------------------------------------|
   B--------------------------------------------------|
   G--------------------------------9--7--7\6---------|
   D----------------------2------2--9--7--7\6---------|
   A--\7--5---------------2------2--7--5--5\4---------|
   E----------0--7--5--3--0------0--------------------|

The chords at the end of that riff are somewhat muddied with
distortion so it's hard to tell exactly what they are.
What I have tabbed sounds similar, though, if not identical.

The same goes for this riff. Correct it if you can:
                   A                G              F#m 
    I found the secret...
   E--------------------------------3---------------2-|
   B---------------2----------------3---------------2-|
   G---------------2----------------0---------------2-|
   D---------------2----------------0---------------4-|
   A--0-2-3p0--h6------0-2-3p0--h6--2---0-2-3p0--h6-4-|
   E--------------------------------3---------------2-|
                  Fm   
   E---------------1--|
   B---------------1--|
   G---------------1--|
   D---------------3--|
   A--0-2-3p0--h6--3--|
   E---------------1--|

I don't know the solo(but would love to, of course).
If you know it, send it to me and I'll put it up.

   outro-  
   E--------------------------------------------------|
   B----------7--7----------5--5---------3--3---------|
   G----------7--7----------5--5---------3--3---------|
   D----------7--7----------5--5---------3--3---------|
   A---0-7-9---------0-5-7---------0-3-5--------3p20--|
   E--------------------------------------------------|

   E------------|
   B--2----2----|
   G--2----2----|
   D--2----2----|
   A------------|
   E------------|
    3x                  then:
   E---6\7--7-7-7-7-7-|--6\7--7--9--9-9-9--------------|
   B---6\7--7-7-7-7-7-|--6\7--7--9--9-9-9--------------|
   G---6\7--7-7-7-7-7-|--6\7--7--9--9-9-9--------------|
   D---6\7--7-7-7-7-7-|--6\7--7--9--9-9-9--------------|
   A------------------|--------------------------------|
   E------------------|--------------------------------|

That's all I was able to figure out.
