Takumi also worked on Richie's 2012 tour.

In the video below is a short interview with Lumpy from 3:22 on.
He built various guitars for Richie. Not only the black-white Sambora model but a couple more he played during the 2004 Borgata show and during the HAND tour. And I think to remember that he also built the silver guitar Richie used for Lay Your Hands On Me on the Crush and Bounce tours.
