This is a great sounding tab. Since guitar is tuned down, the bass sounds exactly like 
Standard bass tuning (EADG). This is the INTRO, try it!

~~~ - vibrato

-----5-5-----6-5~---5-55--3----------------|
-----------------------------5-4-3---------|
--3-----3-33-----3-------------------------|
-------------------------------------------|


-----5-5-----6-5~----5~--------------------|
-------------------------3---5-------------|
--3-----3-33-----3-------------3-----------|
-------------------------------------------|

That is only the intro. Listen to it for the right tempo or else it doesn't sound good.
GOOD LUCK!
