I've heard that story of Harold Knight winning the World's with one. They say he sounded better than most guys do with a short reed today. I've tried to find a video but no success. So, every time I've tried making the noises with one of my tubes, I get too high of a pitch. I've tried letting the latex slack some, and that seems to help, but makes it harder to control. Would more length help also?
