Currently having an issue with my HX stomp where it produces this high pitched noise (usually with high gain sounds): https://drive.google.com/file/d/1wYUsY1VYG3-Y33KQqAe7wfMJ7BCMw6Y-/view?usp=sharing. This audio is recorded with my guitar volume at zero, the sound is produced immediately when I turn on the amp.
I am sending my Strymon Sunset through the FX loop, and that is where I notice the most noise.
Any tips or help?
Thanks!
