In Love Bass

Drop-D
 
I think he uses a pick.
 
Main riff/intro (played almost the whole way through the song):
G|------------------------------------|
D|------------------------------------|
A|------------------------------------|
D|--3--3--0h6--6--0h1--1--0h1-0h3h6---|
 
In the pre-chorus, there is no bass. (The bit with "and lets not ever take it back" etc..)
 
Chorus:
same as main riff but at the end it goes:
G|------------------------------------|
D|------------------------------------|
A|------------------------------------|
D|--3--3--0h6--6--0h1--1--0h1-0h6h5---|
