BR-9 fixed

Finally fixed my Gibson BR-9 lap steel a few months ago. I was so tired of futzing with it, with no good results, so I took it to a local guy who builds his own guitars, he went through it in detail and found that there was an intermittent connection in the pickup coil, that somewhere inside the coil the wire broke. He worked to carefully unwind it to see if he could reconnect it, but the break was deep inside, so he sent it out to get re-wound. A non-vintage solution but better than having a broken lap steel!

In my research I found a really great web site and spreadsheet which lists impedance and other specs for these pickups:

Also learned from their course web site that the BR-9 pickups are easy to work on because the covers can be easily removed.

"P90-style pickups are interest here because they can be {non-destructively} taken apart, enabling the study of how these {lumped} parameters change as the pickup is put back together, one piece at a time!"
It works perfectly and still sounds great! Now at least it's reliable.
