  • There are two connection options:

    * with a resistor on the effect board
    * with a resistor on the LED leg

    ** pin assignment from left to right **

    ------------------------------------------------
    signal input jack

    -1- wire FROM jack input TIP
    -2- wire FROM jack input SLEEVE
    ------------------------------------------------
    LED

    -3- wire TO led cathode ( - )
    -4- wire TO led anode ( + )
    ------------------------------------------------
    effect PCB

    -5- wire FROM the IN effect board
    -6- wire FROM the LED effect board
    -7- wire FROM the GND effect board
    -8- wire FROM the PWR effect board
    -9- wire FROM the OUT effect board
    ------------------------------------------------
    jack power supply

    -10- wire FROM power jack input ( + )
    -11- wire FROM power jack input ( - )
    ------------------------------------------------
    signal output jack

    -12- wire FROM jack output SLEEVE
    -13- wire FROM jack output TIP
    ------------------------------------------------


    I. If there is no LED resistor installed on the effect board,
    install a jumper between the PCB LED (-6-) and the PCB PWR (-8-),
    connect the LED leg to the resistor "in the gap" between the ANODE and the switching board (-4-)

    ************************************************

    II. if there is a LED resistor installed on the effects board,
    no additional jumpers or resistors are required,
    the wires from the contacts of the switch board (-3- and -4-) go directly to the LED

    Thank you very much for your detailed explanation! After reading this, I think I could also use the resistor instead of the jumper and solder the LED 3LED - and 4LED +. I will test that tonight. Some of my effect PCBs have an LED+ connection, but from what I'm seeing by looking at the traces, "PCB LED" doesn't appear to be connected to any other points so I wonder how it will actually works

  • Hi, the switch PCB works great, but I can't seem to find the correct wiring for the LED. Could you explain how to connect the resistor and the LED? Thank you very much; I appreciate all your work

    Choose the quantity you want. For standard PCB, the starting quantity is 5 pieces.
