I have an acoustic bass and a passive bass that need separate eq but ultimately to go into one input on the QSC. When we rehearse I go through the QSC but my partner sings and plays acoustic mostly unamplified, occasionally they will use an amp but rarely. In a live situation I play the acoustic bass through the Fishman, into the QSC and DI out from the back of the QSC, my partner usually DIs straight to the desk and relies on the venue’s foldback, so, at the moment, we don’t share anything.
