Re: Charlie Watts
Sorry, guys, but Charlie used Ludwigs until around Dec. 1966/Jan. 1967. He also used matched grip at that time.
When he switched drums to Gretsch, he also switched from matched to traditional grip. Apparently he got inspired by his jazz roots to switch drums and grips.
Check out photographs of the Stones before '67 and you'll see it: Ludwigs and matched grip. In Bill Wyman's "Rolling with the Stones" and in the compilation book "According to the Rolling Stones," there are multiple pictures of Charlie before he became the Gretsch man we all know and love.
Personally, I think his definitive drumming came after the switch.
