John Molineux box dulcimer
Instruments- discuss specific features, luthiers, instrument problems & questions
The dulcimer in the video is very cool and relates to some ideas I've been thinking about lately (such as fingerboards that do not touch any edges of the instrument)
It's hard to imagine what aspect of that dulcimer would be patented. It is notable that the second fret board does not have strings or a bridge. My first guess would be that it is intended to have a lower register of deeper pitch strings. This seems likely, since it only has one octave worth of frets.
Another guess would be that the second fretboard is meant to play in a different key. Bing Futch has a Folkcraft dulcimer with two separate fretboards in different keys.
Either way thanks for sharing
