I think thats more to do with his choice of pickup, picks, strings, and technique.
While the body wood does make a difference (I believe all chris's new guitars are basswood with maple top) and the maple tops will add a nice sparkling top end to an otherwise "medium" tone wood. I personally feel most of the clarity you are hearing is more a technique thing. Seeking chris play 5 feet from my face twice now I can definitely tell you the mans technique is flawless.
