Notes on 3 guitar parts for Space Cadet (Kyuss)

Still working this one out (as you can tell - especially that 'solo' section). I've made this vid to share with friends so we can work out 3 guitar roles, but if it helps others, great.
0:00 Demo
5:10 Tuning etc.
6:16 Intro.
6:48 Guitar 1 (bass line)
9:40 Guitar 2
12:10 Guitar 3
13:22 Solo (for others to flesh out)
The bass line hooks me every time :)
