I just played an outdoors gig and I set up all my gear and left for about 20 minutes and when I came back my controller and lights were all covered in water! It's winter where I am and the moisture from the air kept condensing on any equipment that wasn't generating heat (so my laptop was fine as it was warm, thankfully). I spent the night with a tea towel over my controller only peeling it back to do mixes and to wipe it down with napkins! Does anyone have any tips for keeping equipment dry?
