FYI - the fretlight does not limit anyone to playing the guitar in any fashion. It's a copy of a Fat Strat, but has an interface built in to show lights on the fretboard. It's a guitar instruction DVD or tablature translated onto the fretboard. It is not an auto-chord type of casio keyboard toy.

Any instructional technique is limited or enhanced by the motivation of the student. Doesn't matter what methodology it is.
