    Hi everybody,
    I have this strange - to me - thing going on on the sub-harmonic feature of my ABM 500 combo: it kicks in only with relatively high gain (i have to keep it at 2 o'clock at least if I play normally). If the gain is lower than that, to hear the effect I have to play louder and it will last only for the few moments after the attack.

    I wonder if this is a normal feature or there's something going wrong there.

    I have to say that other than this the amp works perfectly and I am very satisfied with tone and power.

    Anybody can help me?
