Having no clue about gear or sound, and being morons are two different things; one is a lack of information the other is a lack of capacity. Considering Joe or Jane Average can't tell you what the difference between a bass and a guitar is, we are generally playing to a clueless audience.
However, given the bell curve of intelligence, there is a solid statistical chance that a good portion aren't playing with a full deck.
For better or worse, you can apply the same stats to musicians.
I've rarely been disappointed by underestimating my fellow humans.
This is a little long winded:
I respect your opinion and find no fault with your logic. As far as it goes. For example, if we were discussing the news media and the vast cluelessness of the people sheeple who buy into the #$%$#, your comments would resonate perfectly with my views and feelings. But we are talking about musical instruments. In particular, we are talking about bass amps which are indeed a vital component of a musical instrument, the electric bass guitar. Which indeed is a vital component in many, many groups performing music.
Statistics, information or mental capacity, per se, are not relevant factors regarding why our fellow human beings "like" some bands, and not others. Or why they may prefer certain music vs. other music. The fact that an audience doesn't know what an SVT is or probably isn't even actively listening to the bass player for that matter is actually perfectly irrelevant to whether they want to boogie down on the dance floor when they hear a band they like. A band which undoubtedly would have a skilled bassist, that is, a bassist who statistically speaking may very well be using an SVT since so many popular bands do just that! The audience doesn't have to know why they want to boogie down, and actually, thinking about something like that kills the vibe.
Ritual responses to music like dancing or love making are not cerebral in nature but rather are autonomic responses to loud primal rhythmic and harmonic stimuli. In fact, functional intelligence and logic, per se, is suppressed by these responses which is why they are so desirable and sought after. For example, nobody falls in love by intellectually analyzing the various characteristics of a potential mate and then adding up the score. Why someone is attracted to someone else and can't keep their hands off them is not something people think about like that. Nor do they want to. It's subliminal. Okay, so leaving out the idea of a bass solo, bass guitar in particular is almost purely subliminal. People don't actively listen to the bass guitar or think about the bass they hear and feel all that much. Yet, it has a profound emotional effect on an audience. Don't believe me? Stop playing in the middle of a song.
The point is there is arguably something about the way the Ampeg SVT / 810e combination sounds (when sufficiently cranked, that is) that happens to be intrinsically pleasing and emotionally inspiring to many, many bassists who use the combination when performing / recording. This may indeed lead to a more inspired performance that an audience will indeed respond to. But there's no reason to think that the audience themselves is not cast under the same spell even if they don't know, or care why. It just is, what it is. Groovy!
