FischmungaXTR Posted September 16, 2014 Share Posted September 16, 2014 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? Quote Link to comment Share on other sites More sharing options...
swipesy Posted September 18, 2014 Share Posted September 18, 2014 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. Quote Link to comment Share on other sites More sharing options...
