Is that buzz there when you are plugged into other equipment or just from the AxeFX (I know that it'd be tough to check as there is no headphone output). Have you tried using the ground lift on the back because it really sounds like it'd be a ground loop issue if it's not effecting tube amps which wouldn't be plugged into another device directly.
Yep done the groundlift, unplugged every single PowerPoint in the house etc etc, as mentioned in previous post doesn't seem to happen with other amps. Been through all this on the forum before, I just have to accept it unfortunately.
