Is there a way to invert foot switch lights default on/off? - HD500X in POD HD Posted December 1, 2018 21 hours ago, pianoguyy said: No, you didn't do it on your 500. What you may have done was reverse the effects so that on was off and off was on. But you didn't light up 7 lights (8 less the 1). can it be done... most electric pathways have a + and a - so, if you were to take apart your unit and reverse the wires controlling the lights.... maybe that will work. Do you know how to reverse the effects lights?
