Yes I did try that, thanks.What amp is that - does it have a proper grounded power cable or a DC adaptor? Have you tried using the ground lift from the back of the FM9?

I don't have a Humbuster cable on hand but I tried a TRS cable from the FM9 to the amp - didn't make any difference.A number of us are software, hardware, and chip developers, etc., and also think logically and know how to eliminate variables. We are trying to help you solve this problem, so accept the help in the spirit it is given; you asked for our help so we’re giving it. Nobody is assuming anything bad about you.
The power might be connected, but the unit does not have a software-controlled power switch, so, unless the on/off switch is in the ON position, the unit is not on. It will be grounded though, and being grounded could be the problem if the circuits have different potential as a ground loop could occur the instant the units are connected together, which would not go away when the power is actually turned on.
Fractal’s Humbuster cables can help with ground loops. The manual describes how to build them on p. 6; they’re not the usual TRS to TS cables.
The MX5 worked but I haven't tried the HX effects yet - a friend is bringing that tomorrow. The amp is a little Orange Terror - but I tried it with a Boss Katana artist too - same result.HX effects has a DC power so no earth issues. What amp is it???
A TRS -> TRS cable is different, and won't provide the feedback the modeler needs to reduce hum, nor will a typical TRS -> TS as they'd connect the tip and ring. Again, page 6 in the manual explains how and why it works.I don't have a Humbuster cable on hand but I tried a TRS cable from the FM9 to the amp - didn't make any difference.
Both of those have grounded IEC power cables so I'd expect the same result.The amp is a little Orange Terror - but I tried it with a Boss Katana artist too - same result.
I was a hardware and networking guy before I was a developer - but in 2009 I saw the writing on the wall and made the move. It was a wise move. Plus I got tired of being a cable monkey I'm sorry to say I'm far to lazy to splice my own cable these days. I made my last CAT-5 cable long ago.A TRS -> TRS cable is different, and won't provide the feedback the modeler needs to reduce hum, nor will a typical TRS -> TS as they'd connect the tip and ring.

If you're handy with a soldering iron then it's a simple adjustment to one end, the end that plugs into the amp, swapping the TRS for a TS, and grounding the ring conductor to the shield in the TS plug. The TRS end always has to be connected to the modeler, and the TS to the amp.
Of course, if you're a true software developer, then the hardware and sysadmin guys will run away if they see you approaching any CPU with a screwdriver or soldering iron.
He did say that multiple outlets were tried cuz I suggested the same thing.I hope support can help you out.
I do have one more theory. Is it possible your IEC cable might be faulty or the AC outlet miswired? It really sounds like it.
I appreciate the recommendation - but I have 2 rack mounted Furman power conditioners plugged into separate outlets in my studio desk. I've tested with those and stand alone outlets with the same result. I also have a drawer full of power cables and I've tested separate ones of those as well.So all very good advice here, my 2 cents would be to get a power conditioner for starters, like Furman Power Conditioner (SS6B) for reasonable cost, and if you have a bit more of a budget then Furman AC-215A would be my recommendation (I'm using one for my FM9) be sure amp and FM9 are pugged into the same conditioner, would not hurt to change out the power cable for $7.00 as well as the cable chain, I'd replace them all personally. Wall tester as Unix-Guy recommends is essential imo, in the signal chain be sure you don't have any funny patch that has gain up to a crazy level that amplifying any of the effects in an obscure way,(not even sure if that possible) anyways, try building a flat/clean patch input output shunts only and see how that sounds. One last comment can you hear that sound with headphones pugged in? GL
Do you mean without the FM3?Just tried the proximity thing - that didn't make a difference BUT I did discover something new. As I turn up the gain on the amp the noise gets louder to a point where it actually farts or something - it's doing that click, click pulsing noise at lower gain levels like in my video and bout noon on gain it just does this huge fart noise. While comical - now that means I can't even turn up the gain on my amp.
FM9 - no with - just tried to move it as far away as I could from the amp to see if that made a difference - it didn't seem to.Do you mean without the FM3?
I looked into the Terror Stamp and found this post:
Listen to the clip posted. And read the other comments.
You might consider another amplification solution.
Sorry mate. I’m fresh out of ideas now. Maybe you can borrow a friends amp (solid state basic amp) and see if the problem continues.That is very similar - but I tried it into a Boss Katana and it does the same thing (front and effects loop). I wanted to use my Katana as a power amp so looks like that's a no go.
I wish I had a (good) amp to try with it - but I don't.
Although - if you read his post closely he says only effects loop - whereas I'm going into the front (though I hear the noise with both) and he says it's dead silent when hooked up to a cab - and that's where I hear it. He also says it's quiet and to me it's very loud.That is very similar - but I tried it into a Boss Katana and it does the same thing (front and effects loop).

No thanks a lot - I really appreciate the suggestions. My friend is stopping by at lunch with the HX Effects so we'll see.Sorry mate. I’m fresh out of ideas now. Maybe you can borrow a friends amp (solid state basic amp) and see if the problem continues.
I’m also wondering what will happen with the Helix pedal.
Good luck!
