Fractal FX8 (possible ground loop ?)

Hey everyone,
So I noticed recently my FX8 started to cause what appears to be a ground loop from the output of the FX8 to the Input of the amp.

Couple of troubleshooting steps I did:
  1. Noise is there even if I bypass the FX8.
  2. Noise goes away if I plug directly into the amp even if the fractal is still in the amp's loop (inline or bypassed).
  3. Bypassing loop or removing loop cables, the noise remains.
I am using Hum buster cables, however I built those myself based on wiring diagram here:.
https://wiki.fractalaudio.com/wiki/index.php?title=Humbuster

Going to check all my cables again and make sure all the solder points are good.

If everything passes and still have the noise, anything else I can check?

Any help would be appreciated.

Thanks

Thanks
 
It can be a fuckin nightmare….good luck. I have no idea but I was having an issue with my setup and a cheap Pyle unit handled mine.
 
Yup…

You might get a 3 prong to 2 prong adapter and use that on your axe power cord. Might fix it homie.
 
Anyone else with any input/thoughts ?

I reset system parameters as per finding on fractal forum, but didn't seem to make a difference.

I have humbuster cables built with the TRS end plugging into the Fractal and TS end plugging into the amp.

From further troubleshooting, if I plug the guitar directly into the amp and leave FX8 in the amp's loop, noise goes away. If I bypass the loop and remove one of the connections into it (return or send), noise goes away.

Thanks
 
UPDATE: I fixed the issue with the (older) ebtech hum eliminator. Got one used off of eBay for $75CDN shipped to me. Plugged the cables coming from the FX8 that go to the amp's effects loop Send/Return into the INs of the EBtech and then the OUTs go to the send/Return jacks. All non-high gain buzz, hum, etc.. gone.

and bonus the tone isn't affected at all, at least not that I can tell from just listening in the room.
