just to make sure i'm not totally flaking out, i thought i'd post this. cause i am old and forgetful. i use a cr 1604 mackie for jam night at my house. i bought a cfx12 and slid it in it's place. i get 20%volume even with everything maxed out on board. and effects sound awful. i've tried main out, sub out and utility outj, all 1/4 inch plugs. i don't have cords for the other main output. the break switch is off, the gains are all up. everything i can think of is set like i'm used to. thought i'd post before i send this back to seller to see if i'm missing something obvious. would appreciate any help.
