Hi!
I made a circuit using this scheme: http://interface.khm.de/index.php/lab-log/piezo-disk-preamplifier/
And it works great, I just have to just match the input resistor since the gain is too big.
I need to add to this scheme a simple EQ correction, preferably low and high tones, possibly the same high tones
I've arranged something like this based off a few other schemes:
Is this correct? I have the impression that the correction system will interfere with the Gain potentiometer.
I would be extremely grateful for the help, since it is already one of the last steps to finalizing the project.
