I tried a new outlet, tried turning off all the lights and even unplugging the internet modem/router in case that was giving issues with the bandwidths and whatnot (not sure if that's even a possibility but just wanted to be sure), and the hum is still there.
just saw your latest post about the reverb, and even with it off the hum is still there. i did notice something new and that is when the presence knob is turned from 0 all the way on, it does add an additional hum / hiss, but that's not super important i don't think at the moment.
The hum is present even with the standby switch engaged on, meaning no guitar signal, however when the standby switch is turned off, the hiss gets slightly louder.
Make sure to turn the volume on in the imgur link here. The button to click it is at the top right of the video.
Also, plugging a guitar cable into the effects loop increases the hum
