Hi everyone,
This forum has helped me a lot but this is the first time I'm posting a thread as I was not able to find exactly what I needed.
My dad is an accordionist and we use electret microphone pickup system for the accordion. I'm working on a new system for a new accordion and I want to make this one from scratch instead of adapting the existing ones which limit us to get the result we want.
I'm planning on using "Panasonic WM-61A" capsules (any suggestions are welcomed). I will use 4 capsules for the Keyboard and 3 on the buttons/bass with one volume knob each, internal 9v battery, jack output ("stereo plug" to turn the system on when connecting a MONO lead/cable)
I need help with the schematics as I've not been able to figure out all the components/resistor/etc... I need and where they go as I've been ending up with noises or poor sounding.
All would be connected to a PCB which I can have it done once the schematics.
There are loads of systems out there to install it yourself but there's always something that doesn't reach our needs.
I'm attaching an overview of the system and I'll be thankful if anyone is able to develop it for me but I do understand it's a complex thing.

Thnks SY for your attention mate, I'll study these links you sent me which certainly seem to have a lot more information than what I had found.
The most detailed analysis of the WM-61A I have seen is here:
John Conover: Using the Panasonic WM61A as a Measurement Microphone
There are a lot of options there, which may be confusing, but it may be a useful reference nonetheless.

Electret mics seem to have joined the list of endangered electronic components. Newer cellphones have moved to MEMS microphones, so the main market for electret mics has dried up, and some manufacturers have already stopped making them. (Panasonic among them, sadly. 🙁)
Will we soon have cheap MEMS microphones we can press into service for musical instruments or audio measurement use? I'm keeping an eye open. So far, most of the MEMS microphones I found don't come close to the wonderfully wide and flat response of a good electret mic. Also, most are tiny surface-mount devices, and many come with an onboard A/D converter, so they spit out a digital signal, not an analog one.
