Are you talking about where he kicks in the wah pedal? If so I'm hearing this: First lick is a classic 12th fret pentatonic box blues "roll". Rock your wah pedal while you bend the 14th fret A on the 3rd string up to a B, and roll across the B and E strings at the 12th fret. The first bend and two roll notes should be played with a triplet feel (even though they're straight 1/8th notes). Do this roll three times, then end on the 2nd string 15th and bend it up to an E. Second lick: slide/grace note up to 10th fret on 3rd string and do another roll (no bends) across the 2nd and 1st strings at the 9th fret but end on the 1st string 11th fret and bend that up to an F. Then it's back down the same shape: 1st string 11th and 9th frets, 2nd string 9, 3rd string 10, but end on 3rd string 8th fret. Third lick, starts out similar to second. Slide/grace note up to 3rd string 7th fret and roll across 2nd and 1st at the 6th fret, then 9-6-9-6 frets on the 2nd string, 3rd string 8th back to 2nd string 6th, then 3rd string 6th with a slight bend and pulloff to open (I think the open G is just some classic Page semi-sloppiness/genius), then 3rd string 5th with a slight bend and back to natural, then 3rd string 3rd fret 4th string 5th fret 3rd string 3rd fret. Fourth lick I'm really not sure to be honest. It's hard to make out distinct notes, but it definitely sounds like he's doing something with a G diminished arpeggio. The closest I reckon is some sort of triplet arpeggio starting from the low G on the 6th. So G-Bb-C# on the 6th and 5th strings, C#-E-G on the 5th and 4th strings, then kind of single notes with the wah on each one: G-Bb-C#-E-G-Bb-C# from the 4th string 5th fret up to 1st string 9th, however you want to finger it. Then big E power chords at 7th fret with open 6th string, then slide up to 12 and do hammers and pulls on the 4th and 3rd strings until the gong hits. End on an E7#9 at the 7th fret (E-G#-D-G) with open E.
