Aaron, it isn't about fair. It's more about things like honest and legal. If Mica and Ron say that this bass was not made by Alembic, then it is not an Alembic. Rod clearly knows this now, having read this thread and, most likely, received Mica's email. Continuing to call this an Alembic bass is fraud at best and failure to alter the listing will most likely result in it being deleted. Mica always tries to be nice when the Alembic name is used by someone who has been misinformed, but it shouldn't be allowed to stand if they attempt to continue once properly educated on the matter.
Even if Rick Turner is correct in his assessment, the best Rod can do is to say it may have been, or even probably was made by a future Alembic employee in the years before Alembic began producing instruments. If Frank Fuller is still out there reachable somewhere and can be contacted to confirm Turner's story, then you could say that it was made by him rather than may have been. You could even say that Rick Turner, who was an Alembic employee in the early years, is sure that it was made by one of the other Alembic employees of the day. Anything beyond that is pure conjecture, and actually calling the bass an Alembic is offensive and dishonest, at least to me. Even if it were made by an Alembic employee in the Alembic shop, it still wouldn't be an Alembic.
Rod, It's a very interesting bass. I hope you alter the listing, or restart it altogether, with a more accurate description.
