Noise coming out of effect chain

[CosmosHara]

Today i found out a disturbing issue in my rig.

There will be humming NOISE even if i am not playing a thing.

However, the noise will be canceled whenever i touch any of the patch cables head in my rig.

I think it has to do with grounding?

So may i know is my power supply the cause of this issue or the patch cables?
I am using 6 of same brand/head patch cables.

Thanks.

Hello.

from my experience, grounding of your amp as well as the power supply for your pedals play a HUGE role in removing that hum, you should probably consider that first.

you probably know this by now, but single coils will add a little more of that humming noise as compared to humbuckers.

not sure about touching the patch cables though. i always thought they were supposed to make more noise when you touched them. are you an electrical dump my friend? i kid.

hope this helps.
