volume pedal issues..

  • Second dilemma,

    I use a volume pedal ( mission expression pedal, as a gain boost for leads. I have it set up ( volume pedal) right after the input, pre the stomp section or at least I think i do. I have the pedal set that heel down is off and toe down is on. Why on some rigs it works and others it doesn't, even though they are in the same performance????


    help please


    Thank you.. Angelo
