Solo:

Of course I don't know how to play the solo, but I will type
up a portion of an interview with Tom Morello from
Guitar World Magazine, Dec. 2002. Here he describes
how to perform the solo:

'It's all the toggle switch on the guitar. I have the
toggle switch configured differently on a few of my guitars.
So rather than the normal toggle--with one pickup off,
one pickup on--this one has off, on, off. So it allows
for a 'hummingbird wing' kind of effect.' p. 74

After that part, mess around with your Digitech Whammy Pedal.

-

After the solo, there is a 4 measure rest, during which you
can hear a note being tapped(I think). The note is:

C# -10-|
Ab ----|
E  ----|
B  ----|
F# ----|
B  ----|

Break down:

C# ------------------------------|
Ab ------------------------------|
E  ------------------------------|
B  ------------------------------| X 4
F# ------------------------------|
B  -12\--3-5-0--10-12\---0-3-5p0-|

then


C# ------------------------------|
Ab ------------------------------|
E  ------------------------------|
B  -12\--3-5-0--10-12\---0-3-5p0-| X 12
F# -12\--3-5-0--10-12\---0-3-5p0-|
