I've never had the opportunity to play bass through another Marshall cab, nor have I seen another Marshall cab like this one, whether pre or post Jubilee. At the time I purchased this cab, I did play through the full Jubilee setup (2x15, 410 & tube head) and I was very impressed. But as you can imagine, I walked out the door spending a lot less with the setup you see in the attached picture. I'm kicking myself now. Not that I need it, or have the space for it, but what a cool rig that would be.
I think you are right. This cab would make someones day if they already have the rest of the set. And if I part with it, I would want to see it go to someone who could put it all together. I think there's some history here worth preserving.
