My favorite live/rehearsal 412 is a 2000 mesa straight-slant rectifier with those old basket-stamped V30s,,,,,,,, combined in an X-pattern with a pair of 8ohm k100s.
I wired the cab in the most super simple 8ohm mono-jack method. I think the stew-mac diagram listed it as series-parallel.
For really dialing in the midrange detail I think my stock 2011 rectifier straight is the best. That is definitely the one I would use as a studio cab.
