I would have thought he used a JEM on that record, but who am I to argue with the man himself
I think the PAF Pros were released with the original JEMs, so it's hard to say what was in the Anderson guitar. It could be PAF Pros, or maybe prototypes, or it could be Super Distortions. There was a lot of processing in his sound in those days too, so it will take more than just pickups.
