Buzzing while using my Kemper Stage....

  • So for the past few weeks, or maybe even longer, I have noticed a buzzing in my in-ears but only when I actually play my guitar. When I am muting the strings, it's dead quiet. It's not noticeable when we are playing but if I just play my guitar it's there. I have tried the noise gate but I don't want to have to turn that all the way on. Any suggestions on what might be causing this? Thanks in advance....
