Query: Scam Alert!

"Ralph Paul" Acerno is not a guitar legend at all, but a preacher from N.J. In fact he's a complete unknown who can barely play the guitar, let alone be "America's Best Teacher." He made a video and bought airtime hawking this junk. And it IS junk. I have 2 degrees in music and have played around the country. America has no "best guitar teacher" recognition... (John Abacrombie anyone?). The videos I've seen are filled with errors, both factual, and technical.If I can keep one person from buying this...and seek out a real teacher...I've done my job.I've not bought this, or would I ever... The 20 min of footage I've seen proves its a amateur hack job.
