NOTE: to provide really Whig-esque "wall of sound" you can play empty
E string during the whole riff

Tabbing that b-minor lick by ear really loomed large in my mind,
because it seems that although the time signature during the verses is
4/4, it's played in a very sophisticated way.
I think it's something like that, but rather it's not 100% correct.
During live performances McCollum plays it like that:

E|-2-2-2--2--2-2-2-2-2-2|
B|-3-3-3--3--2-2-3-2-2-3|
G|-4-2-4--4--4-4-4-4-4-4|
D|-4-4-4--4--4-4-4-4-4-4|
A|-2-2-2--2--2-2-2-4-4-4|
E|----------------------|

Solo is also played over this riff.
It is in b minor pentatonic, with wah-wah effect and some bendings.
Start with B on 9th fret of D string.

Two chords just before chorus (or other variations of G and F#):

E|---------|
B|---------|
G|---------|
D|---4--4--|
A|---4--4--|
E|---x--x--|
E|---3--2--|


Bridge/Outro - start on C, then this pattern

 D/F#, G, C
E|---------------------------|
B|---------------------------|
G|---------------0-4b5r4b5r4-|
D|-----0------0--2-----------|
A|---0------2----3-----------|
E|-2------3------------------|
