I just got done reassembling my Squier P-bass after painting it. I pput the pickups back in and everything stayed connected. None of the wires are/were broken. I plugged it into my amp, nothing. In my tuner, nothing. My cables, amp, tuner work fine with my Jazz bass. Could it be that with the magnetic battery powered screwdriver I used to reinstall everything, the pickup has been demagnetized and doesnt work anymore? If so, should I/do I have to get a new one?
