I think this first bit is guitar but I'm not quite sure:

e|-1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~1-0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~-|
B|------------------------------------------------------------------------|
G|------------------------------------------------------------------------|
D|------------------------------------------------------------------------|
A|------------------------------------------------------------------------|
E|------------------------------------------------------------------------|
Use as much vibrato as you like but keep a clean tone

With heavy distortion:

e|------------------------------------------------------------------------|
B|------------------------------------------------------------------------|
G|------------------------------------------------------------------------|
D|-0-0---0~-0-------------------------------------------------------------|
A|-----3------3-0-3-0-----------------------------------------------------|
E|--------------------3-1~------------------------------------------------|
Play twice
============================================================================
NOTE:
The first part should be played on guitar 1, coz its quite quick changing so it'll be 
to put on that amount of distortion in that small space of time. Guitar 2 needs 
of distotion. The gtr 2 part can be played on a bass but the first part can't and
still get a good sound.
============================================================================
~ = very quick vibrato over a very short period of time.
~~~~~~~~~~ = even quicker vibrato using the w/bar.
