I just want to report that I found some minutes to check out a very cheap electret air mic (probably a lavalier clip-on) in a now and here well known French-style way as a contact mic for the bass top.
I didn't expect that this works at all or be of practical use, but was interested to find out if and how it works.
I placed it close to the Ehrlund pickup at a position where the Ehrlund works too.
The mic got directly into my Genz Benz Shuttle 3.0-10T, no mic preamp used (but the signal was a bit weak, I used full gain, some mic preamp might be a good idea to use it practically).
I have not pictures or sound examples (maybe in a week after Christmas), but there were three interesting things for me.
First, I got sound out of the amp which I didn't really expect because the air chamber between top and mic membrane is sealed.
Second, it needs to be sealed completely to avoid feedback. At first I only sealed the front of the mic to the top, but since the capsule was in a small case and had the back open for the cable out, it generated feedback when I turned the bass. After sealing two parts at the back (all with the well-known Faber-Castell putty, but could have used glue for the back too) the feedback was gone.
Third, I won't use it practically, because I got a strong resonance around open G to A above. I have some more electret capsule around here, but need to wire them up to xperiment with them.
I don't have much time left at the moment, but whenever I find some time to experiment further, I will report the results (hopefully with photos and sound examples here. That might take rather long, so I encourage you to buy the French pickup that is known to work well.
I just did this experiment out of curiosity and wanted to share my results for those of you who are as curious as me.
