I'm looking at the possibility of adding temporary outboard graphic eq's (2 channels) to my pa...temporary, until I go digital. I've never been a Behringer kind of guy, but I like the feedback elimination features of the Behringer ULTRAGRAPH PRO FBQ6200HD 31-Band Stereo Graphic Equalizer with FBQ Feedback Detection System...i.e. the led feedback indicators on each band. Has anyone had good and/or bad experience with these units? I know some Behringer stuff is ok (Midas) and some are trash.
