Four-string bass tuned to B (B, E, A, D)

"Wah-oo!" Riff:

D|-------------------------|
A|-4-------7-------9-------|
E|-------------------------|
B|-------------------------|

Verse:

D|---------------------|
A|---------------------|
E|-7---------5---------|
B|------5---------3----|

Chorus:

D|----------------------|
A|----------------------|
E|-4----2----4----0--1--|
B|----------------------|

I didn’t put the strumming/picking pattern in here… But it's easy to figure out.
