Modern Noter Drone Dulcimers

Sometimes it seems as though all dulcimers made today are designed for chording and are equal temperament. I know there are some people that make replica dulcimers that recreate some of the classics. I just received my first dulcimer which is a standard modern dulcimer. I am only playing noter drone style and have learned that dulcimers can be designed to compliment that style of playing. Of course there is still so much I don’t know and I don’t want to rush. I would like to learn more about the possibilities regarding noter drone friendly dulcimers. Maybe I will need to wait for a time when in person gatherings can happen again so I can look, listen and try in person. I am hoping I can learn more about the noter drone friendly dulcimers that are available. Does Just Intonation allow 61/2 frets? I’m wondering if it’s possible to get a modern drone hybrid of sorts. Just Intonation, taller fretboard, flathead, geared tuners and 61/2 fret. I don’t know if I’m using the wrong terms but I haven’t had any luck searching online for makers of dulcimers designed for noter drone or even any that offer just intonation. I’ve seem some that make replicas but haven’t seen any that fit the bill. What’s out there? What are the possibilities? Thanks, Ken
