I’ve been studying the design of Gibson’s classic P.A.F. humbucker guitar pickup designed by Seth Lover in 1954.
As the design evolved, conductive covers were specified in order to shield them from RFI. Nickel was selected for a very important reason.
What does this have to do with audio connectors, and why is nickel as poor of a choice for audio connectors as it is a good one for pickup covers?
