So, I have built a working transistor based mic preamp.
Here is the schematic I used, it's identical in every aspect.

In short, could I use a 10k potentiometer, connected to the input/output of the circuit (and ground) to control the gain? And, if not where could I connect a potentiometer to control the gain of the preamp.
