I highly recommend Tim's masterclass on two note comping at Jazz Guitar Society.
It is priced at the extremely fair price of $20.00 and comes with a great set of handout pages in pdf format. Check Tim's website out for direction to getting this class. Do not let the title fool you, it is also very applicable to and aligned with understanding Ted's many handout pages here in TG land relating to the work that Paul has done on JumpBack Blues, Approach Chord Blues, and the miscellaneous chapter in Ted's Chord Chemistry. Once you get this material, or if you get this material, you might start thinking that the Watson and Crick Model of DNA leads to only one possible conclusion: Paul, Tim and Ted all share some very common genetics. At least that was the idea I got after having previously seen all the other aforementioned educational / musical materials. It's a great addition to Stephen D. Anderson's and Ronald Cid's "Visions." I'd even say it is an essential and necessary colleague of "Visions."
