This is the basic main intro riff first, Satch doesn't always hit the G on the
end though, he does a few little things like raising the volume knob on his
guitar and some pick slides a couple of times aswell but I find it more fun to do my own 
funny noises rather than just completely copy him. The main riff does return a
little later in the song also. Then after the main riff I've included the talkbox
bit aswell.
Listen to the song for tempo. You can listen to it on Joe's official site www.satriani.com.

Ok I think thats about it. Like I said this is just a basic tab of the intro. So
have fun with it.
