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---------|------------|------------|
