My 1962 Standard/LP's back pickup isn't working again and suspect the braided wire into the p.u. is now delicate. Is there a preferred way of removing the cover; I've just looked at Youtube clip involving a soldering iron. If that's the best way what maximum wattage iron should I use? I had thought of going down the knife route thereby not losing any solder among the windings. I may have posted some time ago about how to access the bridge mountings- it has the ebony block with pearl inlays. I discovered that the ebony tailpiece actually slides back from the bridge on its felt underlay.
