First thing to do is focus on the PODxt Pro's outputs.
If you connect a pair of headphones to the PODxt Pro's Phones jack is the hum present in the audio signal? Hopefully not. If there is, then there could be an internal issue with the PODxt Pro. Let's establish what the case is here, first.
Second, if you're running the 1/4" output of the PODxt Pro into the front of an amp, the 1/4" output filter should be set to Stack Front.
Otherwise, if you're going into the FX Loop Return of the MESA, Stack Pwramp might be a better filter option.
There's a Ground Lift switch on the back of the rack; you might want to try flipping that switch in case the "hum" you're experiencing is a ground loop hum.
