I think you may have tapped into a key factor in this discussion that has not gotten much consideration until now.In true Talkbass fashion the thread has assumed a life of its own.
In reading and considering the OP and subsequent comments I am not sure I would want an amp, however classy, that I could not affect via manual controls.
My own sound changes a bit depending on my mood as much as any objective acoustical-electrical data.
I tend to play differently depending on how I feel, how the band is feeling, the song itself, etc.
As it is my amps get gnarly, louder and darker as I dig in or really pound out my lines - and I love that. They match my mood by simply reproducing my playing passively.
How would a “self-correcting” on the fly control-free amp deal with changing subjective emotional playing styles, which can vary in a number of ways?
This is more in the realm of the human psychi than anything else.
People have an almost unquenchable need to be in control of their own destiny, be it in music or other aspects of life. Relinquishing control of matters that personally affect you to another person can be a very scary proposition. Turning over all control to a uncaring, unfeeling machine can leave us with a sense of utter helplessness. Having a purpose in life and having some say in how that purpose is directed is at the very core of being a person. It may be as simple as having an override switch that will take the machine out of the equation. Even if the switch does nothing, we at least feel better in having a switch.
Part of my job is to deal with emergency technical situations. The call I would get was often initiated by an operator who is not normally trained in dealing with these situations. To best assess what is going on I need the caller to be fairly calm and ready to answer questions. If they are going off the deep end, they are no good to me. No one dies when things go wrong. The world will not end. But sometimes it seemed that way to the operator placing the call.
I once installed a large “panic button.” The instructions were, before you call me, press this button a few times until you don’t feel as anxious about what might be happening. I never was able to collect any hard data on the effectiveness of the button. But if it helped give someone a sense if control and brought them down to where we could carry on a coherent conversation, then it was worth it.
