"Its sounds bad. this is 3th concert have same problem. Its an amateur how use Jovi the microphone. Read the users manual Bon Jovi! I dont understand nobody told you this after this years. If i do an FOH or mon mix and one singer do that i told him take some lessons from me, or its the last time i mix for you. I want perfect sound, not this. Its the same if you in an race car try win an race and sit backwards in the car. A millions cost sound equipment wasted of bad handling of one microphone."
"JBJ wraps his hand around the capsule of the microphone almost all of the time (like many of the rappers do, also). This leads to a thin, compressed vocal sound. I am an FOH engineer also and I absolutely HATE it! Horrible attitude and a pain in the ass for every FOH on this planet!"
