Hey, folks! I'm (as good as) a beginner. After reading the reviews of the L&M Series (all of which were positive and highly recommended it), I'm considering asking my aunt to get it for me this June. Has anyone used it? If yes, I have a few questions: *Are electric guitar lessons also provided on the same set? *Are there lessons for advanced techniques like arpeggios etc. and diminished and harmonic scales on it? *Does it teach staff notations? *If the answer to the above questions is 'no', is it still worth $249?
