According to Gibson at least:
http://www.gibson.com/en-us/Lifestyle/Features/top-bassists-0328-2011/#I don't have an issue with any (being in a mild mood today, that includes even JPJ!
) of the gentlemen named (or twenty others they could have named instead), but trust Gibson to forget on their own corporate site an - actually the most - iconic
Gibson bass player like
Jack Bruce.
I re-scrolled again and again a couple of times not believing they would shoot a turkey like that. Gibson has people working on this site who (1) don't know who Jack Bruce is and (2) don't know that he played an EB-3 all through the late sixties and early seventies and an EB-1 again in the last ten years. Because they don't know what EB-3s and EB-1s are either. A-m-a-z-i-ng. They must breed them somewhere.
I am 100% sure had Fender done something similar, they would have listed Jack Bruce and tipped their hats with a comment like "although never really a Fender player except in the early days of Cream when he played the odd duck of the Fender VI ...".
Gibson is so oblivious of its bass playing legacy it sometimes even still hurts after decades of ignorance.
