What are you doing, AltAudio?
1) You have two positive 9V batteries in parallel, not in series. So there is no negative supply for the opamps.
2) Your attempt at connecting the transformer primary to +9V simply shorts the positive battery.
3) A volume control connects to the input of a power amplifier, not to its output.
A pot is simply two resistors in series.
Your circuit has a voltage gain of more than 1160 times which is way too much gain, no wonder you need a volume control.
