Rear of Kemper has a ground lift.
Right?
Tried it?
Yes, I have tried that, but thanks for the suggestion, the ground lift did nothing in my case. I think it's my house wiring... even my playroom has some hum, though less than my music studio.
@Gary_W - thanks for the suggestions. I really do like a lot of the MBritt profiles too, and I'd use more live if I could cure the hum, which is obviously my house's problem, and not his profiles. I mention him more because that's where this thread got it's beginning. There are some profiles I use more than his, partly because the tone matches my tastes better, and some because the hum is easier to eliminate.
The left wall of my music studio I've had examined by an electrician and he says he sees an obvious problem in the original construction there, but he'd have to rip off an entire wall or two to tackle it. So I've been plugging into the right wall naturally. Much cleaner... but... still quite a hum. (You should have heard the left side hum!) The playroom knocks out about 3/4 of the hum, but if I make adjustments to suit that particular room, what happens at a club where I don't know anything about the potential hum issues? The hum could be worse, could be better. I might have to 'gate' it all over again.Hmm... stuck on whether to change anything at all.
A new audio interface isn't really my issue because I'm just trying to play through the amp and my cab (set to off) at the moment, never mind PTools. No, no fluorescent lights in this part of the house... The computer - I'll have to give that a look see... thanks for that tip.
@nightlight - dodgy for sure mate!! Yes, everything appears to be grounded. Grounded and dodgy, like me
