I tabbed this off of one of Trevor's live performances so it should be
exactly how he plays it.
Tuning: Standard
e|--------------------------------------------------------------------------|B|-----3-----3-----3-----3-----3-----3-----3-----3-----3-----3-----3-----3--|G|----0-----0-----0-----0-----0-----0-----0-----0-----0-----0-----0-----0---|D|--------------------------------------------------------------------------|A|--------------------------------------------------5-----5-----5-----5-----|E|--3-----3-----3-----3-----3-----3-----3-----3-----------------------------|

That's all it is. This is just played repeatedly throughout the entire song.
It's really easy to pick up on, just play it next to the song once or twice.
Enjoy and let the sweet sweet sounds of Trevor Hall consume your mind :)
