Today I was attempting to raise the bridge pick-up in my Jazz bass a bit, which involved replacing the foam under it (it had perished away a bit). In the process of doing this, two of the (three) wires have come away. How difficult is this to fix? Anyone got any recommendations for people who would do this?
Also, I've noticed that the pickup is quite microphonic (especially in comparison to the neck pickup) - wax potting doesn't look too tricky - any good advice on how to do this?
Edit: the pickup is a Bill Lawrence J45.
