Here's a clip I've been spreading around the interwebs since I recorded it yesterday morning. I recently purchased a Quad, and it's running through a Carvin TS100 and into a 1960A with G12T-75's and Vintage 30's in an "X" pattern. For this clip, I mic'd only one of the Vintage 30's.

Here's the same setup and settings on a G12T-75:
