I picked up a copy of Chris Brooks new book today. Very in dept detail on the Yngwie method of picking. There’s a lot about downward pick slanting, edge picking and a lot of other terminologies created by Cracking the Code. Troy get’s a mention in the opening of the book as well! There’s a lot of detailed diagrams of how to hold the picking hand, anchoring and how to archive the various pick slants. It’s very good, very in depth and almost feels like an extra part of the Volcano seminar. Would definitely be of interest to any Code fans! (He’s not paying me to advertise this by the way! Haha!)
