I played an original 63 Jaguar. The dual position was bright and chimey as it should be. Mine was not.
So I checked the pickups which were bought brand new, but not as a matched set, just the neck and bridge AVRI 62 reissue pickups. Magnetically, they were reversed.
I had no way to check the winding direction so out came the screwdriver and soldering iron. Within 20 minutes the bridge pickup leads were switched and the guitar was back together.
Perfection in the dual pickup position - all is well. The Jaguar sounds like ---- a Jaguar. One happy builder
