Static / buzz / crackle



  • My setup :
    Telecaster -> iConnectAudio4+ -> Macbook Pro .
    Nothing's peaking on the interface, audio buffer setting set to 256.

    'Jammin/playing' with the A.H.G Wah Lead preset, or any other American High Gain with the gain 'dimed' adds horrible hizz/static/buzz to tone ...
    Sounds just like a broken cheap mobile phone speaker ...

    Increasing audio buffer doesn't help ...

    Also notice this on some low(er) gain "crunchy sounds" ...

    Where should I start lookin' for the problem & solution ?
