Perhaps during the soundcheck he was using his explorer to see how it worked with Angel of Harlem. Maybe he thought it sounded nice, which would explain why he used it on the vertigo tour. I'm just thinking out loud here, but I don't think it was during a show.
I not so sure that The Edge would be out there getting drenched during a soundcheck.
