With the 57, just adjust your mic positioning to brighten things up. The Peluso clip sounds like a 57 in the sweet-spot. Though I don't think the first clip is bad. Could be cleaned up fairly easily with a slight boost in the 3khz, a slight cut in the 700-800hz, and then the application of Andy's C4 setting.
You say the bottom speakers sounded better, but did you flip the cab to get that speaker off the floor before micing it?
