In a stage light dimmer, I have seen many pots with hollow shaft put on one main shaft.

But seriously, I know you post as 'old school' & 'tubes' but that sort of thing is done digital
in a simple way.

An other aternative is use those voltage controlled ampliers on a single pot.,

Dunno about that, rotary encoders, digital...

Touch screen... circle, digital.

Yes, those have 2 sliders inside.

Put listener on rotating podium,
or rotate speakers around listener on rails,
or ...

I'd choose: rotary encoder, PIC, voltage controlled amplifiers.
Would be a real-time enough user response.
