That bass is a Becvar (built after he left Alembic), that is shaped like an Alembic and not a 'ghostbuilt' instrument. It's in addition to the Alembics that JPJ has. It does not pretend to be an official Alembic, meaning there is no Alembic logo on it. You won't see another bass like that done by Becvar because he was warned against building exact copies of the Alembic models down to the headstock shape. He did use our templates to make the body and after that he was told not to use them.
A 'ghostbuilt' instrument is not just a copy with someone else's name on it, as in this case, otherwise you could call anybody's Gibson & Fender copies 'ghostbuilt' instruments; I would define as 'ghostbuilt' an instrument that is copied along with the original manufacturer's logo, like the Ted Nugent 'Gibson' Roman mentions on his website. Since Ed also defines a 'ghostbuilt' instrument as one built by someone other than the regular staff of the manufacturing company ( but, still under commission from that same manufacturer, so it's all legal), I think he contradicts himself on the Becvar bass issue, since Alembic definitely did not hire him to build that bass.
