I install the frets on a dulcimer just before setting it up. Since the dulcimer is built to be resonant hammering in the frets can get very loud!

Hammering frets into a dulcimer can get very LOUD!

I consider hearing protection an essential fretting tool.

It might not be an issue for some when fretting a neck or a dulcimer fingerboard that is not attached to the body but when the fingerboard is over the soundboard it is an entirely different story!

But Wait, There's More!
