And what experience, if any, other than some part time demoing and working in a store have YOU had, Ian...?

You EVER work for Yamaha R&D? Marketing (other than store work)? Read a book (Let's play the Yamaha way!)?

Humor us... just ONE provable fact. One teensy weensy factoid that fits the facts. C'mon, don't be shy...
