Feedback Eliminator

[Roy Dennis]

I have everything plugged into the mixer, from the mixer I usually use left channel to one speaker, right channel to other, sometimes I daisy chain depending on the location. Left & right channels to one speaker then output from that speaker to the input of the other one. they are on speaker stands. I can control the feedback by adjusting the high & low frequency or the gain on the Mic's on the mixing board.
It is just that I wondered if these Eliminators were any good, by your first answer I see you are not impressed with them.
If I don't get any positive responses to this I will dismiss the idea of using one.

Thanks for your response.

Roy.
