Ok so I'm chipping in to help build my cover bands pa. So far we have two 118 peavey black window cabs, and a carvin dcm 2000 feeding them. Two powered Mackie mains, a 20 channel board, 31 band eq. What else should go in there to do small/medium venue gigs? Vocal effects are in planning the stages. Also, the other guy I'm splitting stuff with seems to think we need 7 channels of compression. ... 4 on drums, 3 on vocals, all gated. I was thinking just kick and snare would suffice. What do you all think?
