Pearl Jam — Fuckin' Up bass tabs

(drop d tuning)
main riff
G|———————————————————————————————————————————————————————
D|———————————————————————————————————————————————————————
A|5—5—5—5—5—5—5—5—0—0—0—0—0—0—0—0—3—3—3—3—3—3—3—3————————
d|————————————————————————————————————————————————3—5—3—5

chorus, before guitar solos:
G|——————————————————
D|——————————————————
A|—5————0———————————
D|————————————3————5

That's pretty much it, and there's an improv off the main riff during the guitar solos 
but it shouldn't be hard to pick up
