Default Signal ground and pot

Ok need to brush up on my principles here.

Can some one explain to me why the signal ground must be connected to one leg of the potentiometer and then to the start ground?

because it sets the input impedance of the amp, by running the signal + to - across the full value of the pot.

hope that helps, steve.. ..
