With the values shown, the input impedance is a very low 1k.

Yikes, glad I asked. Thanks.

Very poor op amp front end.
The capacitor should have a resistor in front of to make a low pass filter.
Then 1k input impedance followed by a 100k resistor which does nothing.

Thank you for the input. I'll keep looking for an 'inexpensive' project.

Much better front end.
