I was fortunate to study with Mr. Gordon during my Las Vegas years and he often discussed these 'remedies'.
In fact, one time Mr. Gordons plane wasn't working-he flew his own plane from L.A.. to Las Vegas for lessons- and he paid for my fare to L.A. so I could have my lesson!
At the time Mr. Gordon had a studio in Van Nuys. He had a room full of 'gadgets'. Every gadget that ever existed. And you know what?
Not one of them ever helped anybody.
