Update:
Just heard back from Mica.
Turns out that these are Essence electronics in the bass.
Weird! No idea how it got to be this way.
Anyway, Mica says that Europa electronics are $625.
No way to add switches to the existing Essence electronics so the only way to get it back to Europa electronics is to add a new set.
The good news is that the bass plays great and sounds excellent! Here is a video I just made after changing the strings and setting it up.
I also added some correct collet knobs.
Here are some current photos fo the bass as is looks with new knobs.
