Plus the original poster states that he is a session player, has been using a Series bass for years, as well as other Alembics, and now needs something that produces the Bartolini sound, but with the feel of an Alembic. The last bit is why his only option is to replace the electronics on an Alembic.
His actual question remains somewhat unanswered - Barts are supposed to be designed for a 16 radius, Alembics for 12, and does that produce a problem. (No problem, as suggested by Eugene a few posts up from this one.)
