Staticky clean tone issue

Hi – I recently bought a stealth black hss MusicMan cutlass. My main rig is all digital through a line6 floor processor. When I go direct from my helix to my audient id14’s di or into my computer directly through usb – I get a sort of staticky/fizzy tone that sits sort of beneath my clean tone. It’s audible. Subtle but audible. The folks at ernie ball suggested adjusting the trim pot inside the guitar. Has anyone else had any issues with this and how did you resolve it?

Thanks
