Does soundbox tension affect volume and tone
Instruments- discuss specific features, luthiers, instrument problems & questions
Having set up many violins & cellos etc over the years....You may want to explore using a sound post. Not really a "dulcimer" thing, but you're an outside the box kinda guy anyway. If you Google "adjustable soundposts" you will find much info good and bad about using them in so- called "real" instruments... Bottom line, is that moving the amount and location of tension to the vibrating surfaces [top and bottom] can and does change the tonal qualities. I suggest an adjustable only because there are no standard rules when it comes to dulcimers and the dimensions. Instead of having to re mount your strings, an adjustable may give you more room to play around, or just source some dowel rod and have at it..[or pencils, chopsticks,...] Changing the tensions to the body and try and find the "sweet" spot[s] if any? Then we'll have to find out if heart holes with pointy bottoms sound as good as rounded ones......
just the meanderings of a wandering mind......
