Guitar Strings?
Playing and jamming difficulties...HELP ME!
Diane, the size of the strings you use is determined by the vibrating string length (VSL) of your dulcimer. That is the distance from inside the nut to the place where the strings contact the bridge. If we knew that length, we could make better suggestions. Just looking at the dulcimer in you avatar I would guess you should have the .012s on the melody strings, the .014 in the middle, and what Dusty suggested for the bass; .022 or .024 wound string.
