DuoPhase

sweet build. That thing has some crazy looking stuff on the board! What do the little pots on on the board control? Artwork on it is very cool as well.
 
The pots change the intensity and flashing of the LED, more like a fine tune for the light.

I went with yellow. I guess red would work, but it seems as if it would have less brightness.
 
maybe build each side with different colored LEDs and see if there is a difference in the filtered sound. It may depend on how sensitive the LDRs are to different spectrums of light. maybe the LDRs would even react to an IR or UV led, which might add a bit of mystique to the pedal.
