Basically it's just this for bass, but you can "translate it" to guitar chords if you 
the strings notes basing yourself on the frets the bass line is played. (anyway it's 
the fist part and then A/E/G/G#, just like in the bass line)

E--5--55-55--------I-5--55-55---------|
A-----------3-5-3--I----------0-3-4---|
D------------------I------------------|
G------------------I------------------|

As I say, quite simple! Hope it served you well :)
