Hummingbird Bass Tab

Song's in the key of G (E string 3rd fret) and the entire song for the bassline is just 
G major scale.. I've got some incorrect tabbing for the intro and breakdown at the end 
I'll leave them off here.. figure it out yourself:

(G major scale is G|-----------------2-4-5-|
                  D|-----------2-4-5-------|
                  A|-----2-3-5-------------|
                  E|-3-5-------------------|)


main bass riff is this:

G|-----------|------------|------------|
D|---542-2222|------------|2-----------|
A|-----------|523--5-5-55-|--2-222320—-|
E|33---------|------------|------------|
