These pickups have never been installed. I have opened the package only to check the resistance with a multimeter. View the photos to see the information presented and the condition. Questions are welcome if you need further information. Pickups will be checked prior to packing and shipping. It is recommended to get someone familiar with installing pickups as it only takes a slip of a screwdriver or even a screw to break the fine copper wire and render a pickup inoperable. and for this reason I am selling these as is.
