Hi there,

I've checked your circuit, there are two things need to be modified. 

First of all, you connected the negative 9V to the positive VS+ of your op-am which can burn the device in real life.

Secondly, for your output terminal, you grounded the probe1 directly, which means there will be no output signal at all. You can add a junction(ctrl + J)  next to your R5 and delete the wire to the ground to fix it.

The frequency response from 1 to 20kHz is shown below.

Attached is the fixed circuit.

Thank you very much for help
