Last night I built a circuit that allows me to obtain sound via a SEED Grove Sound Sensor and input it into my MKR Zero for frequency analysis.
It's as simple as this:
You just talk or whistle into the mic and it outputs frequency values.
It works very well but it picks up ambient sound of course.

Now, I'm wondering, could I build that same circuit and replace the electret mic with one of these audio connectors and expect a similar functional experience when I connect an electric guitar?
If you need more details on those see product listing at https://amzn.to/2CkTO0g
Basically, I'm wondering if that amplifier circuit will work to increase the levels from the guitar input enough for the MKR Zero code to read it in the same way as the microphone is being amplified.
Or should I expect that the guitar input would be at a lower level and require more amplification?
