Endorsement is different from designing something for someone - case in point: the Exploiter shape, which was done for John Entwistle. According to the
history of body shapes, John Entwistle wanted the Exploiter body. He bought 15 of them. The Exploiter is a variation on the famous Gibson Explorer design, and it was designed and made for John Entwistle, and fortunately for many others. Elsewhere it states, our customer David Fung designed the Stinger Omega. Or how about this: The first Elan was made for a customer in Japan that wanted a very Jazz looking bass. So body shapes have been designed and made for customers, even designed by customers. This is different, in my opinion, from the issue of endorsements.
The thing that struck me was that the Stanley Clarke shape isn't mentioned at all on the body shape history page, which is why I asked. Well, the fact that I recently took guardianship of one is another reason.
I don't mean to pick on you hendixclarke, but your statement sounded like speculation stated as fact. If you spoke to someone at Alembic about it, or read something in a published interview, etc., then that's another story.
