Do yourself a favour and don't use the EQ of the STACK section but the Monitor Output EQ in the OUTPUT menu (page 3/5). This way your beautiful rigs can go untouched to FOH and recording. And btw, you know that you can save Output Presets? This way it's very easy to switch your Monitor EQ once you have made a few presets.
Good point and yes that is where I am making my adjustments. Unfortunately I find myself adjusting a LOT at rehearsal to get my volume and mix to sound right. It's a constant struggle actually and I'm growing weary of having to do that.
