I play a steel guitar and just bought the vpjr 6180 volume pedal and I don’t get any sound from it until my foot is basically in full toe position. I need it to gradually build volume but instead it’s like an on and a off. There is a tiny switch right under the pedal that moves left and right and I’ve tried flipping it also but nothing changes. What am I doing wrong or is there an adjustment needed or is my pedal defective? I’ve heard nothing but GOOD things about Ernie Ball so I’m hoping that this is just a user error but not to much can go wrong with a input and output jack also a tuner jack? Can someone help?
