X3 Live Expression pedal LED mod

Recommended Posts

I've been having some trouble with the expression pedal not bottoming out properly in certain venues due to lighting conditions, and on closer inspection i've noticed that the expression pedal does not have it's own LED for the LDR, it merely relies on outside light sources.

I was thinking of combating this issue with a bright white 3v  led placed directly under the expression pedal which would create much more stable lighting conditions for the LDR to operate in. All i need is a 3v DC rail!

 

Does anyone know where there is a +3 to +3.4v dc source on the x3 live circuit board?

You may tap whatever DC voltage that may be available, you just need to use the appropriate resistor in series with the LED.  There are many LED resistor calculators online that will tell you what value resistor to use.
