RE: Potentiometer - Volume Pot

It's not the output impedance of what's feeding the pot that matters, it's the output impedance of the pot and that will be determined by the position of the pot.

At the -6db point (equal resistance either way from the wiper) a 250k ohm pot will have an output impedance of 62.5k ohms and that assumes the source impedance feeding the pot is zero ohms. (a 100 ohm source feeding the pot will increase that number but only by a tiny fraction)
