Reply To: Drill for changing strings?
I teach a core group of students how to do this at the beginning of the year and leave it up to them. I think it’s important to practice such maintenance skills as young students so that they are prepared for later life as a musician. We don’t use anything fancier than a hand crank string change tool.
If you use primarily nylon string guitars for class (as I do) you might want to consider putting a set of string tie blocks on your students’ guitars.
