Default low pass filter and volume control pot

why polypropylene need to be smaller than electrolytic in input stage of an amplifier? basically it is a low pass filter. also how do we choose an volume control pot for an amplifier?

It doesn't, however a 10uF poly cap is big and expencive. So you use a lower value poly cap and a higher value resistor........
