This is the main bass riff throughout the choruses/outro

G|------------------------|
D|-5-3----3p0-----0-------|
A|-----3h5----1-3---------|
E|-----------------1-1-3--|

These notes are really 'played' by a backing vocalist, but you need something to play so just...

E|-3--3--3-33--3--

(For those of you without the ability to place tones on the fingerboard)
