On whether people know what an Alembic is ...
I've taken my basses to various venues, open mikes, etc., and the vast majority of musicians I've encountered here (Fayetteville, NC) do not know what an Alembic is, nor have they heard of one. Some of the bass players do, but that's about it. I guess that's due to Alembic's low profile advertising-wise vis a vis Fender, Gibson, etc.
When I lived up in the DC area I encountered more musicians who knew what an Alembic was, but there weren't many.
As far as Stanley's bass goes, I guess one could classify it as an SC even though it doesn't have the electronics of a standard or deluxe SC. I mean, I've got a Spyder, but it doesn't have Series II electronics, two master volumes, note inlays, like John Entwistle's had. Does this mean it's not an Entwistle model? I don't think so. Few of us could afford an exact replica of a famous artist's instrument (unless, of course, they're playing Fenders or some other mass produced instrument). I think what Alembic does is capture the essence, the spirit of that artist's Alembic of choice rather than an exact replica (which would be hideously expensive in the case of the Spyder - I've asked!) in order to place it in more hands. For me, this is OK - I'd like to at least capture some of the magic that such an instrument provides. With my Spyder, I think I do.
My two cents,
