High pitch noise in both Helix and Quad Cortex. Please help

[batrah]

This is not your typical static noise you get from guitars, it's very high pitched and sound like crickets. Even if i mute my strings the noise is still there unchanged. With all my guitars. I'm fking starting to lose my mind. Playing with a clean tone is not possible at all. I live in a tinyhouse on wheels, and the 230v 32A blue electric cable is connected to a garage which is grounded according to the owner. I'm considering installing earth spikes to see if it solves my issue. Do you guys think it has something to do with grounding?

That´s probably electronic interference, maybe like a cell phone or wifi router. Better/more shielding in the guitar might help, if it disappears when you roll the volume on the guitar off.

All you can do is try to eliminate variables: try a different cable, moving the unit or your guitar around, etc. I have a power transformer on the pole outside my house, and it makes serious noise under high gain, even with guitars that are dead quiet elsewhere. If I find the perfect spot in the room and turn 90 degrees, it mostly goes away. Quite annoying.

Try turning things off like wifi, other electronic devices, one at a time to see if that helps.

You're right... I have to physically rotate to one specific direction and it's completely gone.
Thank you

I was going to suggest a power conditioner if it was coming through the power. If it's interference, it's a little tougher. My drummer's basement has a bunch of lights that make my guitar buzz like a mother fucker if I face the wrong way with single coils. It sucks, because I dance and move around when I play.

Are you hooked directly to the unit for output? Is it hooked via USB to a computer or anything like that?

If I sit at my recording desk, especially next to my phone, I get tons of crazy noise. If I just back up 2 feet and turn, completely slient.

Sometimes it's impractical to move away from an amp in order to fix this problem, especially if you're trying to dial it in. I had a similar issue recently when hooking up my amps via a PS-2 to the Axe FXIII. An isolation box works well for this purpose. I have a Radial Headlight that did the job for me, but there are other competing products on the market and I think a lot of people will recommend a Lehle.

If the problem is interference, I haven't found a solution other than removing the offending source. In my case, despite politely asking the power company, they have declined to re-route the transformers to accommodate my need for low noise guitar enjoyment. Next attempt:

If an iso box helped you had a ground loop in there too, and not just interference. Generally the best possible tool to have around, though, and Lehle does pro stuff.

I just tried to power a modeler and a Midi controller with a daisy chain and the resulting high pitched whine was unbearable.

Think yourself lucky. My friend constantly had brownouts on his hi-fi gear, and it cost a fortune.
I briefly moved into a back room with my rig, after a relationship ended. I had an anti-surge plug on the wall behind my pillow.
There was a step-down transformer at the end of the garden, with a cable to the house 15ft above the ground - terminating somewhere near my window.
Laying in bed one night, I watched as lightning hit the transformer, then quickly snaked along the cable, and straight in through my open window to the top of my bed. It actually burnt the quilt and blankets, and there was a huge bang as the surge-protector blew into a thousand pieces.
