Differences between two dulcimers
Instruments- discuss specific features, luthiers, instrument problems & questions
Essential differences? Apple & Oranges!!! EVERYTHING: Internal volume of the body, internal bracing dimensions and locations, plank thicknesses, dimensions of the fretboard, mass of the fretboard (hollow or solid), dimensions of the soundholes, location of the soundholes relative to the bouts, where the nut and bridge set relative to the end blocks, how much length of string between the bridge and the sttring break to the pins, style and material of nut & bridge construction, just for starters.
Wood choices actually play very little part in the sound of the dulcimer compared to the hundred or more other factors. External shape plays NO part in the sound of the instrument.
Choose an instrument first by its sound, second by its look, third by its price, fourth by the craftsmanship, fifth by reputation of the builder.
