Your general opinion of this product.
This thing is AMAZING! My guitarist runs the sound from the stage. Before this, we always had complaints about being too loud, and we fought poor quality sound and feedback issues at almost every gig. Now, our sound is crisp and clean! It even cleaned up the sound coming from the stage monitors! It does require a bit of tinkering to get it tuned just right, but once you do....WOW!! I'd say this is a must have, especially if you run sound from the stage. The only problem we have experienced so far is the feedback suppression didn't catch a low freq. hum, but we killed that with our EQ. Perhaps we just didn't have it set up right. Time will tell.
