    I’m planning to use the DPDT wiring board to add a footswitch for the Ultra Drive Mod.

    Is there a simple way to add an LED that would light up when the footswitch is engaged?

    Thanks!

    Use one side of the DPDT switch to add another resistor to parallel R15.  Use the other side of the DPDT to turn an LED ON and OFF.  If you parallel a 12K resistor with the stock 47K resistor you will change the R15 resistance to 9.66K.

    The mod replaces R15 with the DPDT board. How would I wire it up so that both R15 and the DPDT are wired at the same time?

    Thanks!
