Ive seen a few of these, and I have only seen one of them in use. How do they work? Who makes them, and how much do they cost? I have been playing alot of trombone lately and am in the market for some equipment, and this just might help. If you are wondering what these contraptions look like, they start the same way a normal mouthpiece would, with a rim, then a cup. The difference is that about a quater of the way down, there is an entirely new and smaller cup formed, I guess focusing the air much more. So if you have any info on these things, thank you for your help in advance.
