I also realized that low frequency response only happens with higher voltage and that at 1.5 volts There is almost no low frequency response so it looks like I'll be increasing my voltage.

The size of C3 (In my diagram) also influences the frequency response.

 

You mic already has the jfet built in.
You will need to amplify it, not attenuate it to get 35 mv.
What are you trying to do?

I'm trying to duplicate the output level of this circuit using the fewest components possible with response from 300hz to 8000hz minimum.

 

The size of C3 (In my diagram) also influences the frequency response.

Could I use your circuit minus the voltage divider to accomplish something similar?

I will try to do it tomorrow, minus the voltage divider and see what happens.

 

After more experimentation I realized that the output level is just fine at 1.5 volts with a 680 ohm pull-up resistor and that at 5 volts with the same pull-up resistor it requires 10000 ohms attenuation.

Did this not work?

I couldn't get any low frequency response out of the microphone. Also the noise cancellation feature of the element did not function too well, even though the rear of the element was exposed to the ambient noise.
I have one of these elements connected directly to phantom power and it sounds phenomenal. Here's a picture of how I have the element mounted.

Can you post the circuit you are using?

I tried a 1k pull up resistor as well as a 47uf blocking capacitor as well.

That may be as good as it gets. But having said that, I would move the .oo1Uf to the other side of the 680 ohm.
