Have you made any changes to the default operating levels of the H90? Are they set to instrument level? Do you have anything else hooked up to the H90 in any of the loops?

Is your amp running clean or are you using the preamp’s distortion?

Are you able to film a video showing the noise you’re talking about? I’d be interested to see what noise occurs when you only have the guitar connected to the H90 going straight into the amp.
