I have a used Seymour Duncan Telecaster Pickup. I believe from the tag on the bridge pickup that this is an Alnico II Pro. There are no markings on the neck pickup other than "8.54" so it is possible that it's not a Duncan. Someone suggested it was an import. I got them as a set. I have never tried them or installed them. I was assured they worked when I received them. They came out of a Tele that I purchased and put original Fender pickups in to return it to stock condition. So have no other knowledge of these. If you are unsatisfied in any way I will issue a full refund within the first 14 days. Please take a good look at these before purchasing. Thanks for looking.
