I have two Diesel 2x15's which are both from the early/mid 90's. They have EV speakers. I'm driving them with that 400+. It sounds fantastic and gets so loud it's just beyond stupid. I've used a number of the lightweight cabs/amps and so far nothing I've tried has stacked up to the Mesa rig. Tonally, volume, or otherwise. It can be clean, it can be dirty, it can be a distorted hot mess if you so desire.
I have also driven these cabs with my Walkabout head. It can drive them without issue. Also stupid-loud and sounds fantastic.
Extra fun bone-us round:
I purchased that 400+ from Mike Starr's family when they went through his storage locker and sold a bunch of his music gear. Mike Starr got the 400+ from Michael Anthony when they were on tour together in the early 90's.`popjpeg
