They did that. It was called Club Custom.I don't see any way he doesn't play a Yamaha set per his endorsement deal. That said, they could make him a one off set with vintage shells to his specifications with Yamaha lugs, etc. Yamaha could advertise that and start selling a "New Vintage" high end line based on this set.
Bet I was right about the Rogers….but sizes probably 20,12,13,16. We shall see.Bet he will use 20 12 14 Rogers to be different. The pink ones. He used those in addition to Yamahas on a Mayer tour several years ago. He can borrow my 20 12 14 Rogers if he wants. Just bring them back safely.
