Fixed Bridge and Intonation
Instruments- discuss specific features, luthiers, instrument problems & questions
MOST dulcimers, I would say, have a moveable bridge -- at least somewhat moveable and somewhat loose enough to move (although many builder put a drop of glue to hold thing during the initial string up). Remember, too, that this is a folk instrument in transition, not a concert instrument with 500 years of development. Also understand that there are a couple of "offshore" makers of dulcimers who haven't any real understanding of fret-spacing, intonation, etc. and who seem to be building from unscaled photographs. Like Robert, below, I think you unfortunately ran into a DSO.
When that "Apple" company started, a number of years ago, they were horrendous - 7 out of 10 instruments were mostly unplayable. The instruments were dirt cheap, looked decent (unless you had a good eye) and sold like hotcakes. They've gotten somewhat better (or at least a couple of employees have) over the years, but obviously not 100%.
