Oh man, that reminds me of a "hop" tour I was on. (Where you are in one city doing a show, while a second crew is setting up your show in the next town for the following night.) Anyway, I walk in the next day with very little sleep, and the board is blank! All the presets are wiped and the patch bay had all the pins removed. (Back in those days, analog systems were patched using a diode pin matrix panel.) It was a
DPC show and none of the channels were where they were suppose to be! If I had been more awake, I would have freaked out. Instead, I just sat there feeling each
channel out and patching pins.
