NeuralDSP customer support - bad experience

I’m having muddy resonance/noise that is integrated into any note/chords that I play. It is mostly noticeable by palm muting. Without going into extreme detail of everything I’ve tried, I have tried multiple interfaces, guitars with active/passive pickups, replaced cables, and messed with gains/leveling. I’ve uninstalled/reinstalled DAWs and plugins. I’ve tried a multitude of procedural/physical solutions, such as turning the guitar away from the setup.

Here are links to other people on the forum who have had the same problem:

None of these threads have turned up a solution to this issue.
