I'm in a three piece (2 acoustic guitars, 1 mandolin) revue, and I'm pretty much the sound engineer of the group... we play americana, newgrass, folk, bluegrass, that sort of thing. I've played for a long time, however i'm still a noob to live sound engineering. currently my gear is mackie cfx16, peavey pv2600, qsc rmx1850hd, 2 JBL jrx115 tops, 2 jbl jrx112 monitors (jrx100), 2 audix om-2 and 1 shure sm58 for vox, all instruments via DI or acoustic amp

I'm looking at making some major upgrades to the live sound system... and i want some opinions on whether I should buy all the units seperate (EQ's, compressors, etc...) or a drive rack unit. Also i will be running separate FOH and Monitor mixes. Do i need two separate drive racks, one for FOH and one for Monitors? Any advice would be appriciated!!!
