Snoop Doggy Dogg - Who Am I Bass

The classic Snoop track. It sounds like it is likely a PFunk related bass line as many 

OK, so it starts off with just some build up "noise", I just play something like this 
along with the beat while I wait for the real bass hook to droop:

E --7777777777777777777--

Then:

      (lead in)   (main section core - repeats the whole song)
G  -------------:--------------------------------------------|
D  -------------:--------------------------------------------|
A  -------------:--------------------------------------------|
E  ---0h5p0h5---:--7---77--5-5-7---3-3--2-2----0h5p0---------|

It's funk.. improvise! One variation to play with that you'll hear:

G  -----------------------------------------------------------------------|
D  -----------------------------------------------------------------------|
A  -----------------------------------------------------------------------|
E  -7---7p5h7--5-5-7---3-3--2-2----0h5p0----------------------------------|
