Kings X — Groove Machine (4 String Version) bass tabs

great song i saw a 5 string version on here but i dont have a 5 string 
:( so i'll show you how to play it the way dug does it with a 4


drop d tuning

the song is basically one big riff that starts and stops in several 
different places and its really easy to figure out with the main riff

main riff
g———————————————————————————————————————————————————————
d———————————————————————————————————————————————————————
a—2—0—————————2—0—————————2—0—————————2—0———————————————
d—————0—2—3—4—————0—2—3—4—————0—2—3—4—————0—4—3—2———————

then the guitar drops out and the bass keeps playing the same riff 

then there is a drum solo that lasts like 4 bars maybe and the bass 
comes in with
g———————————————————————————————————————————————————————
d———————————————————————————————————————————————————————
a———————————————————————————————————————————————————————
d———————————————————————————————————————————4—3—2———————

and then picks the main riff up untill the end of the song once 
or twice dug throws in a different ending to the riff but it is just

d———0—3—3—2 instead of d———0—4—3—2

this is only my third tab i have transcribed completely on my 
own please rate
