The way I've always looked at the Clark and King basses is that they (and the EVH and Jimmy Johnson) siganture models are all Signature models. Each may come as standard with a different body shape, but each signature body style and associated scale length is interchangable with the other signature models (if I'm not mistaken)for no added cost. The electronics package (Signature) is the same, as are all (I think) other features offered on the Standard and Deluxe Signature models. Similarly, the custom quote generator includes the same set of upgraded top and back laminates at no added charge, regardless of whether you quote a bass as a Stanley Deluxe or a King Deluxe. I think it's great to designate some basses Clarks, others as Kings, EVH's, Jimmy Johnsons, etc. But when comparing available and standard features, prices etc among different Alembic models, the fact that a bass is a Signature bass seems to be the only critical thing.
Have I got that right? I can't think of any exceptions to what I've said.
