On every preset that have a volume/pan pedal in it i cant hear anything. The volume pedal on the knob draw is turn all the way down and doesnt react to anything i do, while the number is showing 10 (the number is reacting to my actions, you can see it in the pictures). If i want to hear the preset i just cutting out the volume pedal .even when i turned it of (on bypass) it didnt help. I dont have an external volume pedal- i have only the mfc-101.
