I read a thread around here talking about those graphite necks that were make with the Modulus/Alembic logo. Someone correct me if I'm wrong but I think it was (Modulus Graphite Neck + Alembic everything else = Modulus/Alembic bass)
I'm not sure how long the business relationship lasted but I don't think there are many of these out there.
WARNING: Since the necks were bolt on there's nothing that says someone can't dig one of these necks up and slap it on any body they feel like so I have no doubt that the neck is legit but I don't know about the rest of the bass.
