I get noise from my amps all the time. Old house, all outlets on same circuits, all LED lighting in my home as well to keep the energy costs down, so yeah it's noisy all the time anyway, no reason it's not showing up in my captures. Some days are worse than others too, but I'll see if I can figure out how to limit it.
I think that if I make a capture with all the lights off in the house, nothing else plugged in the outlets and use a real audio interface, it might clean them up a lot.
Plus my Stomp XL's USB port is starting to move some and it's noisy anyway, so that aint helping either...
