Hey there Fred – Sorry it’s taken me a couple of days to respond. I’ve been traveling and just now had a chance to dial into that section of the video. So if I understand the question, you are wondering how to get back from the double stop B/G note which is played in substitute for the D/G double stop. The walkdown which follows is 2,1,0 on the A string (C#, B, A)….but, drone your open E string as you walk down each note. I’m also sliding into the C# there.
Does that help? Is that the spot you’re dialing in on? Thanks for the question!
Casey
