Ignorance never stopped me from having an opinion before so...
I have repeatedly confused the Mickey Mouse PU used on Starfires and JetStars with a similar looking pickup made by Hagstrom that is not the beloved Bisonic. Given that Bisonics show up in 1966 my guess is that the pickup in question is not a Bisonic but may, in some way be related to the PU alluded to above. Since the cosmetics differ, maybe come kind of transitional step?
i suppose we should PM Hans and ask him to chime in :wink:
