Just got that one, and using the example for AnalogSerialInput, but I only get 500+-, no reaction what so ever.
How come?

It doesn't look like the output of that board is rectified. Try using a diode, connect the anode to the audio output and the cathode to the arduino input.
Seeing as the OP Amp is powered from a single voltage rail and is DC coupled there is no need for a rectifier.
However, are you sure that you are powering the electret insert correctly?
