My bridge had broken and I got someone to make me a new one, but when I reviewed it over, I noticed they moved the plastic tube to the bottom of the violin. Should I not worry about it or have someone fix it?
Does the bridge have a protective cover glued to it under the string - it's called a parchment? Or does the bridge have an insert in it, usually made from Ebony? If either of these is a yes, you don't need the tube. If the answer was no to both, the tube should probably be there to protect the bridge from the string cutting in. Here is a pic of the two possibilities I've mentioned.
