    Overdrive pedals make my AC30 speaker crackle

    I have a VOX ac30cc2 amp,

    and I have a 808 Tubescreamer, and a Crowther Hot Cake,
    when I turn either of these pedals on, they both add a crackle to the speaker.
    To clarify, apart from the overdriving / gain / distrortion that tehy add, there is also another crackling sound that sits above this, almost like the speaker is faulty or failing.
    But if I play one of my distortion pedals - MXR Distortion +, RAT, Big Muff Opamp, I don't get this extra crackle.
    It just happens when using the Tubescreamer and the Hot Cake.

    Does anyone else experience this?

    i've turned presence, gain, etc. down on both pedals, and am only using them one at a time, but it still happens.
    I also flipped the internal switch on Hot Cake to the Bluesberry option, to see if that helped , but it still happens.
    I also tested it with the amp set to Hot and Warm (back of amp selector switch) but it happens in both modes.

    Can you try those two pedals on a different amp?

    Check your cables is my first goto. maybe a contact cleaner solution.

    I will give that a go, although I did try a few different cables.
    And both pedals do not make this occur to the speaker when I play through my hot Rod Deluxe III combo.

    Oh sorry Malcolm I should have mentioned that I've played them through my hot Rod Deluxe III combo and the problem does not occur
