I saw the original GW video and have to say, I was attracted to the technique but found it cumbersome. What has actually happened over the years is that I have adopted elements of that technique for certain passages and have incorporated it into my arsenal of available options. I have done similar with Anthony Jackson's muting techniques, for instance. What I have as a result is a mixture of several different techniques I can employ at will. I find that GW's technique is very good for a certain kind of fusion/funk sensibility but it sounds overly contrived in, say, a jazz context (his 'standards' cd with Allan Holdsworth is horrible, for instance). I certainly find his sound lacking in something because he doesn't 'dig in' and his concept of swing is not one I would share. A great player, unquestionably, but not a favourite.
