But a 50k ohm pot will have an output impedance of 12.5k ohms at the -6db point of rotation and that will not drive cable capacitance very well.
The output impedance of a AVC at the -6db position will have an output impedance 1/4 of the source.
I've looked at my AVC using square waves and sine waves and I don't see anything to cause alarm. I've even adjusted the source impedance, up and down, and I still don't see any issue that should cause alarm.
Maybe you can show us the ringing that you think is problematic?
