Would appreciate any words of wisdom regarding FOH and monitor mix guidelines for the following outdoor gig I am helping put together. Our band is playing in the backyard with the equipment and sound facing away from the house to a large open area with a row of tall trees about 75 feet back. We'll be using a couple of JBL 925's (2 way 15") with a powered sub for FOH. Have a lexicon reverb unit and decent 30 band stereo EQ (split for FOH and monitors)in my rack for effects and a Mackie 1604 board. Your thoughts on EQ issues/guidelines are appreciated.
