Thanks Don,

My thought was to use a small Mackie board ahead of the main PA system for everything. It has 4 XLR/1/4" channels w/trim/3 eq pots/volume sends and main volume send. Each instrument has it's own eq needs...all different. I can use a DOD A/B pedal to go back and forth between the 6 and 12. The mando and harp are more feedback prone and require more attention. I've got a guitar inline eq I planned to try out on the Harp when it gets set up. The bass eq works really well w/t mando, so I'll leave that alone.

Again, thank you for the input. The whole set-up is a work in progress. Dialing it all in is going to take some time. I'm going to have a banjo on stage, eventually...not to play, but just to frighten people.
