Sound deference between a teardrop and a hourglass dulcimer?

Hi Everyone

I have a question concerning thesound deference between a teardrop and a hourglass dulcimer. I have made three dulcimers, one teardrop, one hourglass that was kits, and one hourglass made from scratch.

Both of the hourglass sounds grate, but the teardrop does not sound very good at all, I also have a friend that has a teardrop, it dont sound very good either.

My question is this, is this common with teardrop dulcimers?

I like the looks of the teardrop very much, but Im afraid to make another one.

Thanks

Ron
