    Boss GE7 Schematic

    I have attached the schematic.
    This unit, like an awful lot of pedals, is not a true bypass when it is "off".
    The switch is labeled at the lower right.
    It goes into that x circuit which is a set\ reset flip flop.
    This turns Q4 & Q5 on & off. (FET's)
    In bypass mode, Q5 must pass the signal & Q4 must block it.
    Monitor the outputs of each and I think you may find which one is misbehaving.
