Stones' Beast of Burden guitar tone.....

[MBreinin]

I have been noodling around with Beast of Burden...I really just want to nail that intro part. However, I can't seem to get the right tone going. Sounds like it may have a little phaser or maybe a chorus on it. Does anyone know how to nail this tone? I have always loved this little rhythm, and finally got around to figuring it out....just can't get the tone right.

Also, what do you think Keith is using on this? I am trying to nail it with a Les Paul copy...I don't have a Tele...but it almost has an inbetween pickups on a LP sound.

Anyone?
