Thanks guys very close trenchlord! I spoke with Mesa today and got some good details. Its from July 25 2007 so I got a dead mint oversized cab for 465 bucks! I got a few other interesting tidbits. you can tell if its an oversized cab by counting the vertical screws on back. 4 is normal 5 is oversized. I also wondered if running in stereo at 4ohm is louder than running at 8oh and he said no that unless its a mismatched the volume is the same. I was curious about that since I plan to run two amps into it in stereo and save me time unhooking things or when I want to record both in a single take (JVM410 and Road King). Peter
