http://www.youtube.com/watch?v=BvAdgDcM9X4 The song is played on Bass, but same applies to guitar. Tuning is Drop C So drop D. Then a all strings whole step down. So tuning should be CGCFAD. This isnt the whole song, but its the basics. Its pretty simple to workout the rest based around this. Bare in mind he probably uses effects pedals on some parts to shift the pitch.
