I am in the process of putting together a cover band that will likely play lots of places that will need us to bring our own PA. I have a very nice set up for rehearsal, but I am thinking about upgrading my board. I was toying with the idea of getting a mixer with digital effects but I can't figure out if the effects are assignable to specific tracks or just to the mains. And I'm not sure how many effects you can run at once. Anyone have one of these? How do they work / sound? Specifically, I am interested in compressing three vocal tracks and the kick, and occasionally adding other effects (delay, whatever). What's the best way to do this - a board with effects or a board + an outboard effect unit (and then what should I look at getting). Also, what boards do you all have good experience with? Thanks in advance!
