For monitor mixes.. either for himself or everyone, if everyone else gave him instuction.. normally I point at my guitar and then point up and they know I want more guitar in my monitor.. I've never once pointed down..
Also, with national ac5s, they'll use what are called side throws, which are PA cabinets on the sides of the stage pointing toward the center of the stage.. I love side throws.. total immersion in my screaming guitar.. I've only gotten to use them a few times.. one of the perks of being in a national act or opening for one..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
