You may be experiencing a USB ground loop from your computer.
I've noticed that the inputs on the FM3 seem to pick up way more USB ground loop noise than my other devices.
The Input of my Kemper does not pick up any USB ground loop noise from my computer via the USB powered DI, as soon as I switch over to the FM3, boom! all that noise comes in.
This will eliminate almost all of USB ground loop noise. Works like a charm.

Yup, agreed... I have two of them they are very good at filtering noise and they have a nice long cord too which I especially like.I've used this power strip for the last 3-4 years and can't recommend it enough. Inexpensive surge protection with EMI/RFI attenuation, I have one at home and one in my gig bag. Reduced some of the computer/monitor generated noise at home as well as some lighting system generated noise in an auditorium.

How do you mount it to your rack? Or do you?I've used this power strip for the last 3-4 years and can't recommend it enough.

Yes I did just the other day, thanks for the follow up 22frets... you should know its on my desk, thanks for reminding me! very good shipping btw... Kudos to you and your post too! as I'm always looking for anything that can reduse RF and or cycle hum....... I'll get it hooked up later this evening if time and wife permits and report back!@DaveO, did you get your USB isolation box? Any report? I am having the same issue. Thx.

No brainier for a USB noise reduction solution since its the first one I have ever seen...
I'll do a FM3 recording with and without and post it.

I believe the threshold changed by 20dB from the Axe Fx II to the III.There's an issue I have with FM3, right from the first firmware I had it with (1.06). Gate settings on FM3 need to be quite agressive in comparison to Axe Fx II (+15dB average !!), which impacts dynamics. Offset 0dB in both units.
Any possible major cause (offset ?); both units are used in the exactly same environment. I am playing close to the unit (say guitar at 1 meter approximately) at my place. Ground lift switch doesnt't change anything.
Any help would be welcome. It's a subject as for some patches it's not imaginable to let this go through FOH.
Edit : I have a Axe Fx II mark I so no special sauce input circuits or the like
