Perhaps "a go to cab" and not "the go to cab". i've been gigging since the 70's and can say without hesitation that I can count on one hand the number of times I have seen an Ampeg 810 cab in a club. And that's from gigging in Canada, the States, Persian Gulf, Switzerland and France. Any band touring around is not looking for opportunities to move more gear than they have to. Furthermore, it's easy finding a great sound without resorting to an 810 cab. Bass players should be playing in a band context and not focusing on being out front of everyone. Plus, loading in and out every weekend with large furniture has not been necessary for 40 years, which is why you seldom see them on stages. I focus more on my playing and sounding great than how I look.
