Do they make Guitar Floor Processors with +4db stereo inputs and outputs?

[fingerlickingravy67]

attention all guitar gear nuts, I wont go into detail about my setup but I need a multi effect processor to add to my rig, needs to have stereo ins and outs like rack FX and can handle +4db line levels. I know rack systems meet all these requirements but would like it if someone made something similar but in a floor box with stomp switches and an expression pedal. Does it exist?
