There is only one bass line in the entire song. its really simple and kinda catchy.

G|-------|--------|---------|----------|
D|-------|--------|---------|----------|
A|-------|--------|---------|----------|
E|8---33-|-55--33-|-8-8---33|-3--55x-33|

and it just repeats throughout the whole song

the bass comes in at [1:03]
