Yes, it is either passive or not, can't remember which. Still has the poles on the back which you can rewire (solder) for your particular taste in sound, you just have to pry it from the pliable goop which holds it to the plate.
There isn't a Bartolini name on the pick-up. They weren't manufactured that way. If you go to the Bartolini website, they will probably be mentioned there as well as more detailed photos. That's the best I can do with the camera I have. Thanks.
