While I admire the work of Mr. Vai, IMO, all of us who use and love the Axe's are the most effective ambassadors for the product. Those of us who, day in and day out, rave about this product to friends, band mates, skeptics in other forums, etc, are the ones helping to spread the Fractal gospel. It certainly doesn't hurt to have the endorsement of well regarded guitar-slingers associated with your product. However, the hundreds/thousands more of us everyday players who buy and use the Axe's are, in my opinion, a far greater testament to the innovative and dedicated work that FAS does to advance and enhance guitar craft. Think of it as a grass roots movement of musician's slowly bringing more musician's into the fold.
