I put them on the Dulcimers and for my dulcimer, it made a brighter sound but I did not like the sound, but I like how the they were easier to play. I just did not like the sound on my dulicumer with the strings.
The Black Coated Mountain Dulcimer strings are wonderful. They make the dulcimer so much easier to play and give it a beautiful mellow sound.
I love the black coated strings. They sound wonderful and are easy to change.

So far am enjoying the sound they make and definitely like how they look against my black ebony fretboard.
