My latest dulcimer, started around 1983 and finished in 1999. It features internal drone strings that double as truss rods, fretboard raised off the body but attached to the back via a dowel, pressure bridge and a soundboard too hard to allow much volume, as compared to its sister built for Constance Cook, with a cedar soundboard and twice the sound. Sides made of sycamore: Don't use sycamore. It cracks.
