Mberg Ultra Light Titanium Fine Tuner for Violin or Viola

I think these are likely the best available. Incredibly smooth...

an excellent accessory

This is the finest quality fine tuner available. The others are more common but do not perform as well. To me it is absolutely worth a little more money.

surprising impact

I am impressed! There is added smoothness for both violin and viola along with a nice fullness on the violin e string. It added refinement that I didn’t expect. I will recommend it to my students.
