Yeah, it's an American phrase allright. I'm not sure where it originated, but imagine chewing on a dry corncob rubbing all over you and sticking to your face, then buttering it up and it gets REAL smooth and flies away. It's sorta like that. I mean that the action and the neck profile is so comfortable, so refined for such a large neck that there is no hinderance - nothing holding you back. You want to play 1/16 or 1/32 note triplets? It's as fast as any guitar I've ever played. Gives me goosebumps just thinking about it. Sorry, gotta go play that baby right now, it just plays like BUTTA!
