Hill E "string guard"
I installed a Hill e string (ball end) recently and there was this small disk of rubber or leather that came with it. From what I can tell, it's called a "string guard", but it's much different that the typical tubing that sits on the string at the bridge.
I installed it as a vibration dampener where the ball meets the fine tuner. It seemed pretty good at first, but then within 2 weeks the thing shredded.
Can anyone explain the right way to use this thing and whether it adds anything to the set up?
Five months from now will mark the 80th anniversary of receiving my first violin. So I have seen many, many of the leather, rubber, and felt string "donuts" (or " bagels" depending on your preferred inclination) and tiny tubes. I have puzzled over them long and hard over those decades and used them in many ways but actually not used them more often.
