Boy, not sure if that's the right word or not, but maybe I can translate better. At 3:34 to 3:36 here http://www.youtube.com/watch?v=mlygg7g9mlA you can hear what I'm talking about. I know Andy doesn't use a recto, but is he accomplishing this "squash" as I'll call it by using the BB pre on a clean channel or is this all Plexi? Maybe that's just in his fingers too, but I love how the amp reacts like that.
