So I just bought a rack with a GBE400 head and a couple effects. There is a Peavey QF131 EQ and a Alesis 3630 compressor/limiter. This is my first big rig actually, so from what I understand,I need the signal to flow out from the send jack, trough the devices and then back into the amp. and I wonder if I need to plug in the eq before the compressor or vice-versa. and second, do you guys think those devices are actually useful? I already have a limiter on my gbe400 and the peavey eq has a larger range than my speakers could ever produce. So any opinions would be apreciated thanks !
