I recently purchased a pair of nickel silver covers to replace those on my Casino and I was a little surprised to find the pickups are actually soldered to the stock covers not attached with an epoxy. I've attacked those solder joints with my 40w pencil iron and a small butane torch and I'm not getting that solder even close to it's melting point so I can remove the stock covers and replace them. I'm being cautious not to apply too much heat for too long so as not to destroy the pickup itself. Have any of you ever done a similar swap and run into this issue? If so what did you use to melt those solder attachment points so you could remove the cover? I know some solder has a much higher melting point but damn even the pencil thin flame from the torch isn't melting it easily.
