Performing musician of 15+ years decides to go for the big PA. Musician mind you, not sound engineer. BIG difference. Just need some help here. LOL Ok, first of all, is the "Alto Terminator" Feedback Eliminator really going to help me with onstage feedback? How much feedback might come from the front of house? What is the placement of the eliminator in the chain of FX? Secondly, is the Alesis Midiverb4 still considered a good effects unit for drums and vocals? In fact, I have several questions about live sound, so if anyone could help, I would greatly appreciate it.
