The two guitar parts I’ll show you in this song are not in standard tuning. Both guitars are tuned to: D, G, D, G, B, D. All you have to do is drop both your E strings down one step to D and tune the A string down one step to G. Keith Richards is guitar 1 and Mick Taylor is guitar 2.
I’ve broken the intro section up into 2 parts. Here’s what the entire intro sounds like with both guitars, bass, and drums:
