Well, for the last hour, I have been trying to find out which chords are used in this song. Guitar is kind of low in the mix, so I don't even hear it well. I think that two chords that i've heard are:

E 6
B 6 8
G 7 8
D 8 8

Steve Lukather has indeed interesting style of playing.

I recently tabbed this song, I think My tab is resonably accurate, just search for 'Rockmaker' and you'll find it, hope this helps
Thanks. I think it's a great tab. I'll give it a rate when I check it out whole, since I already figured the solos out by myself .
