The weird LED/green wire combination represents an optocoupler. I've used the VTL5C2 in 2 of my builds. Here's a nice read about them optocoulers and LED/LDR combo's: http://home.orange.nl/fvrijswijk/guitar_electronics_diy/flatline_compres...
The flatline is really suitable for use on bass and can even give a nice boost to drive a tube amp into fat crunch!
