Stomp on/off weird noise

  • Dear all!

    I have just encountered a weird problem. I loaded up Mats Nermark's "MN Two Rock TS-1 Cle" Rig. It has a boost in Stomp 2, a distortion in Stomp 3 and another distortion in Stomp 4. When I turn on distortion in Stomp 3, turn it off again and then turn on Stomp 4, there's a weird noise (listen to it in the attached file). The same happens when I turn off Stomp 4 and then turn on Stomp 3 again. I loaded another rig and then came back to the "MN Two Rock TS-1 Cle" - problem still there. I shut down the KPA and after a minute started it again: Problem still there. Is there anyone here who has that Rig in his Kemper and who can verify whether this is a problem of just my unit or whether it's common? Thanks!
