I bought this for my son several months back and he never used it.  This is the system that has the lights in the fretboard--you can plug into the computer and learn songs and manipulate the music any way you like.  You can see all teh details at Fretlight.com.  I unpacked it and wiped it down and tuned it up--thats it.  I purchased it directly from Optek Music systems.  I don't know much about this as I never even plugged it in.  I have all the associated software and cables and it will be shipped in the original packaging just as received by the factory.  I just don't have a need for it.  I payed $479 with shipping, I'll trade it for something of equal value or sell it for $250 cash.
YOu can also email if you have any questions or want additional info or pictures.
