Hi, I have problems of hum noise in high gain amp, I have a Boss Eband Js-8 to use it as interface, but recently I wanted to act it and I bought a Behringer UMC 404HD and the hum is unbearable, a friend lent me a Focusrite Scarlet 212 and I had The same problem, the strange thing is that with the Boss Eban Js-8 I do not have anything hum, and when I say nothing I mean 0, someone knows how to solve this ?, or if they recommend an interface that does not have a hum The amp hight gain ?, I also noticed more hum in Revalver 4 than other amps sim, I really do not know why this happens, I hope someone can help me, thank you very much.
P.D. I have a notebook, it is not a problem of ground loop because it probe alone with the battery and using headphones, with studio monitors disconnected from the interface.
