Thanks for so much more info. I will have to take some time to digest it all. I see right now that we can be smarter about initial sound check. Although, when a bar's house pa is blaring CD's I would think it would be hard to "tune to the room." To answer a few questions... The feedback destroyers were hooked one the the mains, the other to the monitors so all mics/pickups were going through them. I don't know what kind of pickups are being used. Various types I'm sure. We discussed much of your ideas last night so now we have a few more tricks in our arsenal. Thinking back, it is possible that we never reduced the trim from the initial set up and we should have in order to turn up the main faders. It is possible too that the Feedback Destroyers were cutting out too much because we did get some "weird and quiet" results. As for the house noise, it was *mighty* loud up there. I got to the point where I was pointing at the setlist to indicate what song to do next or we would pass the word individually from one to another. We got tired of shouting. Ah, what how we suffer for our art.

Cheers, annamora
