I have used these on my custom McSpadden 6 string. They seem to last forever, and produce a nice smooth, mellow tone. With a nice Folksy sound as well. Plus they look killer on this Dulcimers Ebony fingerboard and Black Tuners. Just a nice artistic touch besides the amazing sound and quality.
The black coated strings play well. There is less friction on the wound strings. I do hammer ons and pull offs, and slide from one note to another and it's easier with these strings. They sound great and play easy.
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.
