I have this mutilated hack job of a J-style bass that has one J-style OBL humbucker in approx. "Ric" bridge pickup position (plus two reverse P's in larger housings in Lee Sklar positions). I also have a '91 4003 and decided to compare how close they sound (Ric naturally with only the bridge pickup on). I'd say you could fool people with the mongrel Jazz when you don't hear the real thing. If the pickups were similar the results could be even closer.
