The hum canceling pickup in my Series bass has become loose.  It appears to be connected in the center, but not on the ends and pivots up and down on the ends. Are there any suggestions as to how I can secure the hum canceling pickup?  Thanks!

OK, I found this...

I'll give this a try (but open to other suggestions is new methods have evolved).

Thanks.
