Default Potentiometer value for Zen v4

I could not find any general rule of choosing potentiometer value for amplifiers.
Which value will be better for Zen V4 10k, 50k, 100k or it does not matter?

It does matter a bit. The input impedance of Z4 is 47K,
so you want the potentiometers maximum output impedance
to be smaller than that.

The maximum source impedance of a potentiometer used
as a voltage divider (the output = wiper) is 1/4 the value
of the pot.

A 50K pot would give 12K, which would be the maximum
I would recommend.
