Two and half years in and know these 5 box patterns (scales) fairly well. I read about diagonal 3 & 4 note per string scales that allow one to traverse the fretboard diagonally by leaps and bounds. The finger stretch and hand shifting needed for 3 or 4 nps scales sure seems awfully excessive for these 60 year old paws. If most everything is available in a box, anything wrong with being "stuck in a box" or am I missing out on some big time guitar playing ecstasy? Does a "box" guy equate to an amateur and a 3nps guy a pro?
