Following a corporate mutiny resulting in the resignation of Ray Ayotte from his own company and the subsequent end in partnership with Gregg Keplinger, Cameron switched to Yamaha in 2002, and Cameron's subsequent time with Pearl Jam is notable for his shift away from maple-shelled drums, arguably the most popular drum material for its overall even frequency response and overall melodic tone. Cameron began endorsing and using Yamaha's Birch Custom Absolute drums in a vintage natural finish that year. Compared to maple shelled drums, birch is higher-pitched with a quicker attack and produces fewer overtones. By 2009, he began experimenting with another type of wood, the Yamaha Oak Custom in a black gloss finish with Yamaha Vintage Maple hoops, similar to his old Ayotte's. Oak drums are noted for their additional attack and projection, with a similar fundamental tone to maple. He used this kit through the period of Soundgarden's reformation.
