Loud noise while profiling a high gain amp

  • Hello,


    I tried to profile my Jet City 100HDM (Soldano Hot Rod+ circuit) and when the send cable from the kemper it's plugged in the amp while i'm in the main profiling menu (1st step), it makes a lot of noise with the guitar volume at 0. If I unplug the input cable on the amp it's dead quiet. If I plug directly the guitar it's dead quiet.


    It's not a ground loop, I tried that and made even more noise when lifted.


    Is this normal?

  • I recorded a video.


    Is this normal? The noise is very loud. The guitar doesn't make that noise and it wasn't a ground loop.
