Q: Am I only the one having 1.5kHz and 3kHz rogue freq?

There seems to be a whistle/buzz at intervals of 1500 Hz, with 3000 being the loudest.

Here is my previous feedback made about my preset: Q: Am I only the one having 1.5kHz and 3kHz rogue freq? - #10 by sledge76

Thanks for confirmation feedback. You are the first person having the same issue. It means there could be more similar cases?
However, there is a slight difference. My device has 1.5 kHz as the loudest noise peak and 3 kHz as the second loudest. So I understood 3 kHz noise as the 2nd harmonics of 1.5 kHz.

I’ve emailed Neural Support with a video (that they requested) showing the noise and how it goes away with cuts to 1500 and 3000 Hz. I’ll post back with their response.

Making modest EQ cuts with very narrow Q at 1500, 3000, 4500, and 6000 helps without seeming to make much noticeable impact on the tone, but it’s obviously seem than ideal.

The cross over noise gate posted above is interesting. I have to run the cross over much higher than 700, otherwise the tone gets super dark when rolling down the volume knob.

@sledge76 Try a buffer in front of the Quad Cortex. That seems to remove the 3000hz whine that I hear.

Here is a silly clip of me turning on and off a buffer, and I hear the whine disappear when the buffer is on
