True, but I don't know when Steve acquired the house (I suspect it was after World Slavery tour)Or you can say that room is quite similar to the one in Holy Smoke video (I didn't check the video, but this was first thing in my mind when I saw this picture ).
This bass is hideous. The headstock is just cherry on top.
Also, could it be that Dave used that Mesa Boogie on some of the solos on NPFTD/FOTD? I always tought that his sound got somehow more smooth during that period... I contributed that to the CAR Jackson with Duncans, but now that I see that Boogie...
