Hmm.....I don't know why they wouldn't work if they're dry.
We had a flood in '96 (well, not according our homeowner's policy, not actually a flood, as it didn't come in over the foundation walls, but rather backed up from an overloaded sewer system; yeah, pretty nasty - and a $5K payment on a $75K loss); I got all the guitars out before it changed from water to sewage, but my Epiphone Sheraton did get a bit wet. When I dried it out, it worked fine - until the harness rusted beyond repair and it quit 10-15 years later.
If nothing else, I learned 2 things from it: 1) Don't keep your instruments in the basement, no matter how finished it is, and 2) Never rewire a semi-hollow that lacks a back door..........
