intro/verse riff:
E|------------------------------------------------|
B|------------------------------------------------|
G|------1---------1---------1---------1-----------|
D|----2---2-----2---2-----2---2-----2---2---------|
A|--2------2--4-------4-1-------1-0-------0-------|
E|------------------------------------------------|


then you add in the distored electrice and i think it goes:

E|----------------------------------------------------|
B|----------------------------------------------------|
G|--------5-----6-------------------------------------|
D|-----5--5--7--6-------------------------------------|
A|-----5--3--7--4-------------------------------------|
E|-----3-----5----------------------------------------|
this is also the riff used during the solo, i think.
