are you using it as an audio interface? does it buzz for all audio? If only on guitar, how about input 2 for the guitar?

Not exactly. It is generally chassis GND current riding on the sleeve/shield line running between two different pieces of gear that are connected to each other. You can't have a ground loop with only one piece of gear, only ground noise from the supply.The noise from a ground loop rides in on the power line, not the guitar. Neither the guitar or a noise gate will affect a ground loop. That's how we know that this situation doesn't involve a ground loop.
Except, of course, if there's a circuit fault somewhere inside the unit, or a floating ground somewhere inside. Then it could have an internal ground loop that is causing the buzz.Not exactly.

If the FM9 is not connected to another piece of equipment either via an audio connection or UBS, then agreed, no ground loop.
The guitar only muddies the water, as it may affect the function of noise gates.
That could happen, yes, but it’s not likely to be the cause in this case because the noise stopped when the OP unplugged the guitar.Except, of course, if there's a circuit fault somewhere inside the unit, or a floating ground somewhere inside.

You might be able to systematically power things off and back on and eventually isolate the culprit, and ask if that one thing can be removed, and live with the ensuing silent treatment for the remainder of the holiday season.Update:
Took the FM9 to another place altogether and it seemed fine. I am just gonna chock this up to my wife's 1000 christmas LED's and other powered devices.
I was terrified there was an electrical issue inside the FM9 itself. I don't think that is the case.
Might be worth the silent treatment if the noise floor of his FM9 is silent as well......You might be able to systematically power things off and back on and eventually isolate the culprit, and ask if that one thing can be removed, and live with the ensuing silent treatment for the remainder of the holiday season.
“Uh, well, I thought I’d ask. I’ll be in the music room for the rest of the month, ok? The doghouse? It’s out back. Oh, I’ll be in the doghouse for the rest of the month. Gotcha.”Might be worth the silent treatment if the noise floor of his FM9 is silent as well......View attachment 130811
Tried it everywhere, still buzzy as hell. Guess I have to wait until the new year when all the decorations come down lol.Well how are you going to use your FM9 at home now. Did you try it in another room?
there's a simple solution for this: cancel ChristmasTried it everywhere, still buzzy as hell. Guess I have to wait until the new year when all the decorations come down lol.
Because she allowed him to buy an FM9. Obviously.The real question is why is he allowing his wife to buy 1000 lightbulbs.... ?

quid pro quo baby! lolBecause she allowed him to buy an FM9. Obviously.
Shielding your guitar (pickup cavities, control cavity, jack cavity, etc.) can definitely help to reduce interference. But shielding of your pickups can never be complete, because part of the pickup must be exposed to the strings.Has anyone had success with shielding guitar pickups etc.?
