I have a chance to get some Sadowsky J pickups (hum cancelling) for free. I am trying to figure out when they were made. They are different from the current ones (I think) in that Sadowsky is stamped/engraved in the pickup cover just below the pole pieces. Does anyone know when they stopped doing this? Now a question. Should I pop these in my Standard Jazz in place of the stock Fender pickups? I know, dumb question, but I thought I would ask. The reason I can get them for free is that my father-in-law bought a Hamer Cruise 2-Tek and it had the Sadowsky's in it. Then he saw that TB'er luknfur had some Suhr J pickups for sale. My father-in-law is a guitarist and he has a sweet Suhr strat so he bought the pickups and put them it. I have to say, they easily as good if not better the Sadowsky's in my opinion. I will get some clips of the Hamer/Suhr combination when I go up for Easter. Impressive! Thanks in advance for you help with this.
