Fixed a live mix that was screaming like a cat in a microwave

Spent two hours today untangling a church sound system where the kick drum and vocals were fighting to the death. Turned out the subwoofer was wired backwards—no one noticed because everyone was too busy trying to 'fix' it with EQ. The moment I flipped the polarity, it just... settled. Like the whole room exhaled. Dogs in the back row stopped twitching their ears. Sometimes the problem isn’t what you’re hearing—it’s what you’re not noticing.
