Upon plugging in my newly acquired 80's vox venue amp, I noticed a huge amount of fuzz/noise which I sound determined was coming the internet powerline running through the house. It seems to go away only when I unplug the powerline (makes sense, less noise in the mains circuit).Is there any cheap alternative around this without having to unplug my powerline every time I want to jam? I'm assuming your standard power extender with surge protection won't work and I need some sort of noise filter?
