yeah, Charlie's a bad dude. I've seen him at the Variety Playhouse and Smithe's here in ATL. I have that same amp too, I believe it's an HD-130 w/ two 12's...it's hard to tell for sure though.
Yeah, he's superbad. I saw him years ago with Michael Franti's (Spearhead) previous group "The Disposable Heroes of Hiphoprisy." His groove on "Music & Politics" is sick.
