Just put this little thing together for my pedal board, but its causing quite a bit of noise. Casing is plastic, as I figured that would make grounding easier. Anything I've missed? Just ****ty components? All cables in it are shielded.

Re: DIY patch bay ground noise
It appears that you are using single conductor wiring. In that case, twist the wires around each other. Each pair should be twisted individually. That would be the best way in such a configuration.

DIY patch bay ground noise
Not one wire ....single conductor wiring. .
Each set of jacks has 2 wires, essentially creating a loop. Those 2 wires should be twisted together. You’ll likely need to rewire since the current wires will be too short to twist.
Edit:
You might want to somehow label or color code one of the wires so you know which is which when they are twisted.Last edited by Gtrjunior; 07-28-2018, 11:03 AM.

Re: DIY patch bay ground noise
I've now tried re-soldering. Top one is shield wire connected ground to ground. Bottom one twisted wires. Problem still persist. Thoughts?

Re: DIY patch bay ground noise
Are you getting additional noise or same amount of noise, with or without using the bay?
Use two conductor wires in there, like in the last pic, makes it easier to work & function. I cant tell how thick the conductors are in the first pic, its better to go with thin ones, or they might be as thick as a thin speaker cable, that could pickup more noise. Even with the two conductor wire try to go as thin as possible.
The grounds should match on the respective outlet too . Like e.g. make sure the send/ return input has the matching grounf to the send/rerurn output of that box.
If you are running the amp & pedalboard on different outlets then that can cause noise bugs too.Last edited by Hank-; 07-30-2018, 12:10 AM.

Also amp & pedalboard is on the same mains outlet?
Haven't tried it with the rest of the pedal board yet. So far I've only connected guitar through one port at a time and then directly to amp.

And how are the cables shielded? I see two wires on each jack. On a shielded cable you have the ground and the signal wire. The shield is the ground.
Are you rubbing coax without the shields grounded? That will produce hum.

What does rubbing coax mean?

I think you have your two wires reversed. So the shield is hot. That will cause hum.
If you are using coax why did the first picture show two wires on each jack?
Also what are you patching together? If you patch two different pieces of AC powered gear you can introduce ground loops.
