Re: Adding Some Edge with Jody Jazz
Actually, let me rethink the material on that. Something like Dental Wax would work a lot better (and safer) and would be pretty easy to come by too. And it's easier to form and experiment with. Silly Putty would certainly work well, and you could even use Play Doh. Doesn't have to be anything fancy, just needs to get the job done.
Some of my colleagues have been using created baffles in their mouthpieces and it really does make a difference in edge, and you can get some unique and wonderful outcomes with enough experimentation.
If you find a design/shape/size that you really like and want to have a more permanent baffle, plumbers epoxy putty is the recommended choice (though with the temporary ones it's so easy to fix and maintain that I see no reason in making a truly permanent one).
