I don't remember seeing one with these upgraded electronics.

Hm, Alembic-approved piezos?! I wonder if they ever become an option on the 'horizontal' instruments ...

Adriaan; last August Mica stated in another thread that Piezos are not available as an option ... the resources needed to have us do it would be hard to justify.  And prior to that she stated we've done experiments with piezo pickups before and weren't happy with the sound for basses.

That was what I remembered - just that the Ebay auction suggests that the piezos were installed at the factory. And perhaps the sound is acceptable for a wooden bridge like the Classico has, just not for brass. So what if you have a brass bridge with wooden saddles? Ah, questions, questions ...
