    Just a technical question out of curiousity.

    I had noise in pedalboard.

    Trying every pedal and chain I came to the point that the looper (TC Ditto x4) - the last before the amp - make that noise but ONLY
    1) when it is connected with any other pedal (s)
    2) and feeded in the same chain (I have chain feeding, I knower it is better to ger Power Supply, I will, soon)

    No noise
    1) If it stays alone between guitar and amp (but still fed through the same chain with mny pedals!)
    2) It is in the chain but with separate adaptor

    So it looks like either it should be fed separately ot it should be alone in the chain.

    Why could it be?

    Yeah some pedals don't play well with others.
    The solution is isolated power supplies.
    It is usually the case with digital pedals like loopers.

    It is called a ground loop, where more than one path to ground creates a loop that picks up hum.

    Thank you.
    I guess Power Supply like Voodoo Lab could solve it?

    Depends on the model. You need isolated power and they don't all have that. Voodoo Lab - Pedal Power® ISO-5

    My ground loop tech dates from the era when you cut and splice yourself.
