Did I invent that method of hooking up the input transistor? Sounds good so far...forgot to test the gain control but it's probably okay.

Boring stuff:
I got the idea after reading this (long) explanation of transistors:

The notion of two depletion regions was new to me, and led me to the idea that the transistor will conduct signals in reverse as long as the bias voltage requirement is satisfied. It worked, so I tried it in the circuit.

The transistors seem to be extremely sensitive in this configuration, like the way MOSFET's will pick up every little noise. Hmmm...
