I bought a used a w Jeffries dulcimer in 1970. The friction pegs were a bear to keep in tune so I didn’t play it much. When rheumatoid arthritis deformed my hands a luthier suggested substituting violin pegs. I now attend an annual dulcimer festival with classes and love playing it tuned to DAA. My dulcimer is numbered 453 and one of Jean Ritchie’s sons sampled it and commented it had the very traditional sound.
