Yeah, I've noticed this too. Noticed it for a LONG while actually, I got through once in...96? I think it was, and boy, I couldn't hear either of them for crap, but especially Drew. I think I got through once after that when Drew was on, and the same thing. Last time I was on Drew didn't say much for the Germany of Florida, but I had already blasted the volume control in anticipation. And he mumbles like CRAZY, it's like Adam has said, he seems so bored with his own answers that he has said a thousand times, and words with a gajillion sylables in them, that he prefers just to mumble through them.
Hard to bring it up during a show though. You'll either get put on hold, hung up on, or ranted at about giving them a hard time, or all three. And chances are they wouldn't change it anyway.
