Greetings I was recently having the same problems of getting extreme static/RF while running the pod farm through a UX1 on my laptop. i also tried everything , testing different cables , different instruments etc etc. The I simply thought to take the charger off and then it was gone.
I had to record dry signal to be used for reamping , but when i sent the a small sample before proceeding further with the whole album recording , i got an email from the sound engineer saying that all the levels were fine but the only major problem was this static RF.
The qestion is , if there is any way of eliminating the static/rf (and no, noise gate is not an option) when the charger is on because its creating a bit of problems.
If not then maybe nuying something else would be the best option , even if not desired considering that i spent money on line6 because i thought would be the best for that.
