Fair enough Steve,
I would recommend setting footswitch 1 to rig down, footswitch two to turn on and off your chorus, and then footswitch three rig up. Then, set rig one to be your normal clean, and rig two to be exactly the same amp just with say 3db more on your output, or rig volume, or even our booster engaged that will give you a volume boost. This would only be the three footswitches on the device itself. You could set up the two button footswitch to engage tuner and maybe something like a delay, or reverb on and off depending on what you need.
This is all assuming you only use the one amp sound!
I hope this is helpful!
