Check again, is there really no difference at all when you switch from low gain to high gain when not playing music?
I can only notice a very minor difference when switching back and forth.
HMMMMM...
If that's the case i might upgrade to the PE... GODDAMNIT...
Will let you know tomorrow. But really those might the tubes? Do you have any sources interference near your amp? Like phones? Since that was the only time I had slight hum on high gain with Envy. Really doubt there is any meaningful difference between OG and PE tbh
