I’ve not done a D/C combo yet. It would take a prototype and maybe a few tweaks to get something ready for production. I got an initial design together, but lately have been much more interested in the higher pitched flutes, and put most of my effort into getting an “F” flute design ready to go.
Well, I talked to Casey the other day and I’m on the list for just such a beast. I’d never really thought about low-A flutes till the last few months, when I’ve had to transpose both Altan and Chris Norman tunes (more than 1 of each) up from A so that they could be played on D flutes. I dunno that I’ll have much use for a Bflat, but there are a lot of tunes out there that are played on C flutes that just don’t sound the same on a D flute.
Thanks for the heads-up, Doc; I’d been thinking of an A, but never would have thought of adding a C body to it.
