This line is from a song we do called "Invincible". We have talked about using the thumb as a kind of pick in other segments.
This is one of the first songs I wrote using this technique and sound. For bass it works nice, because you can start a song or a breakdown with this, and then when you move down to a more heavier, or bottom position, the dynamic will kick in hard. To really make this have a nice sound, you will want to use both the hard mute technique, and palm mutes, keeping the line as tight and bouncy as possible.
You want to be locked in of course with the groove, but since it is the same notes playing over and over, you can do different variations for each turnaround.
