Update:
I did went over a list of things last night on the stage unit and nothing seemed to have fixed the issue.
So I thought "I'm early enough into the game only having used the stage for a week...maybe I accidentally adjusted something I wasn't suppose to....so what do I have to lose?" And I did a factory reset. That fixed it. I'm still getting some humming but the tone is on point. I use single coil guitars almost exclusively so that might be what the problem is. It seems to get worse the higher I run the preamp on the apollo. But there is definitely a huge different between profiles now as before they sounded the same with different degrees of gain and sounded thin.
thanks again to everyone for their help and expertise! Much appreciated
