    I have a big muff that works fine but the L.E.D. light does not come on when the effect is on? I checked the wiring & even changed the L.E.D. I made sure it was wired correctly, but still no light? what do you think it might be?

    Does the LED have a + connection? Does it have a – connection? It needs both to light up.
    My guess is its not connected correctly/come un soldered if you replaced the LED and it wont work still.
    Check the Limiting resistor is working too.

    I did change the l.e.d. and checked the connections and changed the limiting resistor. still no light and it still works fine. Any other ideas anybody?

    The long LED lead is the positive one.
