At a bible festival where a band is playing. The band’s amplifier (purple and grey) surround sound configuration fails. The band is the only act at the festival, so people are in panic mode.  Briefly I think separating the amp from the lighting system works, but unfortunately this attempt doesn’t fix the sound issues. Instead my attempt worsens the issues and switches sound from 3 keyboards to 1 small, 1 medium, and 1 large. Band sounds different as they try to play Ferrelli’s with just a keyboard and guitar. They won’t let me help attempt to fix it anymore and I am disgusted cause they sound like shit.
