Ambugaton

Intro riff 1:
E|----------------0-----0------------------------------------------------| 
B|----------4-----------------4-----4-----4------------------------------| 
G|----3------------------------------------------------------------------| 
D|-0-----0-----0-----0-----0-----0-----0---------------------------------| 
A|-----------------------------------------------------------------------| 
E|-----------------------------------------------------------------------| 

Repeat X4

Riff 2:
E|-------------------------------------------------------------------------| 
B|----------------3-----------------------5--------------------------------| 
G|----3-----1--------------------------------------------------------------| 
D|----------------------4-----2-----0-----------3-----1--------------------| 
A|-4-----4-----4-----4-----4-----4-----4-----4-----4-----------------------| 
E|-------------------------------------------------------------------------| 

Repeat X3 (staccatto) allowing for a rest of one beat between each riff

Then repeat X3 (legatto) without the rest (ie - keep the riff rolling!)

Then I think the next riff is this.....
E|-----------------------------------------------------------------------| 
B|--------------------------1---------3----------------------------------| 
G|---------------------1---------3----4----------------------------------| 
D|------3---------4------------------------------------------------------| 
A|-4---------2-----------------------------------------------------------| 
E|-----------------------------------------------------------------------|
