loose EQ knob anyone?

    i recently notice that my treble EQ knob are not as tight as other EQ knob, its easily scrolled which i dont like and sometimes its scrolled down the value by its own, anybody has encounter this and any solution?

    I noticed the same on two of the rotary knobs.
    I have no problem with the valuta changing by themselves
    I contacted Kemper support. First they said that I must have used to much pressure/ violence on the knobs.
    I asked how the pots are fixed to the chassie.
    I thought I could tighten a nut if I opened it.
    I got tehe answer that it must be a fault inside the pot and the KPA had to be returned to the seller.
    If I open the chassie the warranty would export.
    I have not sent it back yet. The pots is of to low quality I'm afraid.
