There have been some hints dropped to the effect of Jean's bass being a shop night bass-- and it definitely has the Alembic Vibe.
Specifically, Jean stated that it started as a current production bass, and you can definitely see the triple omega influence (the bottom half of the bass definitely looks like the top of a production triple omega).
That would make it the most extended range bass ever built *at* Alembic, but yours is the most extended range built *by* Alembic.
