Okay guys, this is my first tab, if I mess up somewhere along the way...sorry.

I prefer Drop D

E I------------------------------I     
B I------------------------------I
G I------------------------------I
D I---3--3--7--------------------I
A I--3--3---5--------------------I
D I-3--2-------------------------I

That repeats 3 times then...

E I------------------------------I
B I------------------------------I
G I-----------------7-5-7-5-7----I
D I---3--3--7-------7-5-7-5-7----I
A I--3--3---5--------------------I
D I-3--2-------------------------I

E I------------------------------I
B I------------------------------I
G I------------------------------I
D I-2--------2-------------------I
A I-0--0-000-0-0-----------------I
D I------------------------------I

Keep on doing that but after each round of the tab above, move up a fret on the D 
string. It would be 2 then 3 then 4 then...

E I------------------------------I
B I------------------------------I
G I------------------------------I
D I-5-------5b-------------------I
A I-0-0-000-5b-------------------I  Ending #1
D I------------------------------I

E I------------------------------I Then ending of the rounds are different
B I------------------------------I I will show them all.
G I------------------------------I
D I-5-------7-5-7-5-7------------I
A I-0-0-000-7-5-7-5-7------------I  Ending #2
D I------------------------------I

E I------------------------------I
B I------------------------------I
G I------------------------------I
D I-5-------5b-------------------I
A I-0-0-000----------------------I  Ending #3
D I------------------------------I

E I------------------------------I
B I------------------------------I
G I------------------------------I
D I-5-------7-5-7-5-7------------I  
A I-0-0-000-7-5-7-5-7------------I  Ending #4
D I------------------------------I

That whole section (beginning of the main riff on the A string) repeats again then 
goes onto this riff.
 
E I------------------------------I 
B I------------------------------I
G I------------------------------I
D I----3---3--7------------------I
A I---3---3---5------------------I Repeats 4 times
D I-3---2------------------------I 
 Notice that you kinda hold the low D
before you strum the A string and the high D string.

E I------------------------------I
B I------------------------------I
G I-7-5-7-5-7--------------------I
D I-7-5-7-5-7--------------------I
A I------------------------------I
D I------------------------------I

I think this is the chorus

E I------------------------------I
B I------------------------------I
G I------------------------------I
D I-2-------3-------4-------5----I
A I-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0I
D I------------------------------I

That riff repeats 8 times

First solo (Oh Boy!!)

E I--17p15---------17------------I
B I----------20b22---------------I
G I------------------------------I
D I------------------------------I
A I------------------------------I
D I------------------------------I

E I-17p13-----------------13-----I
B I-------15-----------15--------I
G I----------14-----14-----------I
D I-------------15---------------I
A I------------------------------I
D I------------------------------I

E I-12-13-----13-----------------I
B I--------15--------------------I
G I---------------14-15-16~~~~~--I
D I------------------------------I
A I------------------------------I
D I------------------------------I

This part I'm not quite sure about

E I-17p13------------13h15h17p15p13h15h17(tap this note)18p-I
B I--------15----15-----------------------------------------I
G I-----------14--------------------------------------------I
D I---------------------------------------------------------I
A I---------------------------------------------------------I
D I---------------------------------------------------------I

E I-17p15p13--------------I-------13------13-17-------------I I improvised on
B I----------15-----------I-----13--13--13------------------I after that with
G I------------14---------I---14------14--------------------I those notes
D I--------------15-------I-15------------------------------I Sorry guys :(
A I----------------17-15--I---------------------------------I
D I-----------------------I---------------------------------I

It ends with this note

E I-----------------------I
B I-----------------------I
G I-14~~~~~~~~~-----------I
D I-----------------------I
A I-----------------------I
D I-----------------------I

Then do the same riffs as before up until the solo above obviously.

Then it goes in to this riff.

E I-------------------------------------------------------I
B I-------------------------------------------------------I
G I-------------------------------------------------------I
D I-2--------5--------5--------2--------------------------I
A I-0-0-0-00-3-333-33-5--------2--------------------------I
D I-------------------5-555-55-2-222----------------------I

E I-------------------------------------------------------I
B I-------------------------------------------------------I
G I-------------------------------------------------------I
D I-2--------3--------5--------2--------------------------I
A I-0-0-0-00-3--------5--------2--------------------------I
D I----------3-333-33-5-555-55-2-222----------------------I

Do the same riff again

Second Solo (I'm only gonna show you the part that I know, cause I improvised most of it)

This symbol "~" means fast picking

E I-151719~-1917151417151415~-15------------------18b2018p1618b20--------I
B I-------------------------------18b2018p1618b20------------------18b20-I
G I----------------------------------------------------------------------I
D I----------------------------------------------------------------------I
A I----------------------------------------------------------------------I
D I----------------------------------------------------------------------I

E I-----12-14p12------12h14h15p14p12----------------------I That's all I know
B I---13--------13--13--------------13--------------------I The rest I just
G I-14------------14------------------14------------------I improvised.
D I-------------------------------------------------------I
A I-------------------------------------------------------I
D I-------------------------------------------------------I

It then ends like this
Turn your guitar down to the point where there is no sound, then start
turning it up again.

E I-------------------------------------------------------I
B I-------------------------------------------------------I
G I-------------------------------------------------------I
D I-------------------------------------------------------I
A I-0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~-------I
D I-------------------------------------------------------I

Then play then chorus riff again then play this riff

Ending riff

Remember this "~" is fast picking

Each of them are 2 beats longs

E I-------------------------------------------------------I
B I-------------------------------------------------------I
G I-------------------------------------------------------I
D I--2~-3~-4~-5~------------------------------------------I
A I--0~-0~-0~-0~------------------------------------------I
D I-------------------------------------------------------I

Repeat again

E I----------------I Use whammy bar to raise the power chord
B I----------------I
G I----------------I
D I--7^------------I
A I--5^------------I
D I----------------I

If there are any mistakes, I'll fix them
