Please help problems with hum

[Dafter777]

Hello everyone! I have an Aria Retro Classic 1532 electric guitar. I play while sitting next to my PC, and my guitar pickups receive electromagnetic radiation. By the way, everything is fine with the cables.
When I play my electric guitar through a NUX MG-400 processor into a Behringer UMC 404HD sound card, there is a hum. The hum varies depending on the physical distance. I want to buy some kind of device to eliminate noise. Tell me which one would be best
Behringer micro hd400 or di box behringer di100 active or alctron di120 passive. I have inst buttons on my sound card and they already give a linear signal, so I would like to buy behringer micro hd400 but the thing is, will it be able to qualitatively remove noise like ground lift in behringer di100? I just don't want to waste more money, since the second one is more expensive

That's what humbucker guitar pickups are for. And/or shielding. Noise that varies with physical proximity is a different issue to ground loop noise.

A lot of PC cases these days are also not properly shielded, with clear windows, and large holes in the metal structure.

Are you saying that behringer 400hd won't help?

Probably not. If the problem isn't ground loop noise, then galvanic isolation is unlikely to help.

Is the noise still there if you plug your guitar directly into the behringer?

Hum destroyers like the behringer are designed to eliminate noise that happens due to the electrical interactions of devices that are connected to each other, not noise that is being received by the pickups on your guitar. Humbucking pickups are designed to reject outside interference that makes it into your guitar pickups.

I feel and hear grounding noise. I think the behringer won't hurt me. Yes, there is a little noise. But when I turn it on without a card, through headphones into the processor, the noise is greater. Friend, tell me. If I play nux mg 400 + behringer umc404hd do I need to turn on the inst button so that it becomes an instrument input? Or does my processor already give a linear signal and there is no point in turning it on? It's just that when I turn on the inst button, the sound is louder but there is more noise. And this is when the gain on the card is at zero. And when I turn off the inst button, the sound is too quiet, I have to set the gain knob of the sound card to the middle. But there is little noise at the middle. I don't know whether to turn on the inst button or not if I play through the processor

I'm not sure, but I wouldn't think you'd need a high Z (high impedance) intrument input when connecting to the output from a digital pedal board. Under those circumstances, there is not direct electrical connection between the guitar pickups, and the input on the audio interface. Just a line level from the effects unit.

As for grounding noise, usually grounding noise doesn't change as you move your guitar closer or further away from a computer.

There is noise and they gave it away too. Let's see what happens, I hope for the best. Thank you very much dear!
