I have a PODxt Pro, I recently started getting terrible EMI Interference noise (its not the 60 hz hum) on all outputs Digital. and all analog outs ie Balanced, unbalanced, headphones....... Its not guitars, cables, output devices, or external surrounding electrical devices........... when I was trouble shooting noise source ie... ground loops, firmware, surrounding electrical devices,.... all of which I think I have ruled out. I have one question, I never noticed that the internal POD power transformed hummed, even though that is not what I hear from outputs.
Can anyone tell me if this is normal with the POD xt Pro power transformer to hear the 60 hz hum when device is powered on with no inputs or outputs connected?
Thank for all replies in advance,
