Lee, after I get new (or re-charged) batteries in my camera, I'll take photos of the new addition and post them on my page at Friends of the Mountain Dulcimer. As an aside, I may start a photo gallery on the Rosin the Bow
group there for folks with bowed zitters of any kind. I like having a bowed dulcimer presence there especially for those at FOTMD who may never have heard of such a thing. (If not for my coming to ED, I may never have heard of the BD. Since there are folks on FOTMD who are not ED'ers, it's good to have some BD information there.
Back to your questions, Lee, my Pardessus is a three-stringer. The viola strings on it are tuned Dad and are in the same pitch as my Standard. For now and, though probably not ideal, for the foreseeable future, I'll be using a cello bow. The sound is more mellow than the Standard due to, I think, all the strings being wound.
Regarding the fretless critter Deb and I tried, I really didn't pay enough attention to note any possible differences in finger pressure or tone. The thing on which I was focused was how the feel of what note was where was already in my 'fretting' hand. I liked the fretless a lot! What are you finding with your OV as you spend more time with it?
No BD workshops this summer for me; Pilot Mountain was my big festival this year.
