Fran & Gary, great thoughts, thanks, I have copied your advice to a word doc and will put it in my mixer bag and get to the gig early to try some of this.

I struggle with feedback since we are trying to minimize our setup time by just using the main speakers behind us. Also, I find my mic channeled through the keyboard booms sometimes as it is picked up by their mics (when I'm talking or singing alone). Maybe I have over eq'd the keyboard, taking Fran's point. I'll look at that.

Many thanks

Graham
