I don't understand the fix. If it's loose tighten the peg. If it's unwinding, I'd suggest you just buy a new one, they aren't that expensive. They have string in all price ranges. Great shop!!
Of course.
They can also show you the correct way to do it yourself.
I'm sure they can
I am a student and i don't trust my self to tighten the strings
It took me a while to learn how to tighten strings. A chromatic tuner helps.
Definitely don't try to tighten the peg yourself, so many of my student's parents have broken a string doing this! Shar can fix a loose or broken string on a violin, viola, or cello
Maybe!
