I’ve got one of these. As you can see it looks like a rather cheap Boehm flute and it sounds like one too. The embouchure is in no way different from a standard Boehm embouchure (if there is such a thing as a ‘standard’ Boehm embouchure). A nice conversation piece but not a flute any Trad player would want.
I have one of these too. There is a Boehm-ish quality, but it’s also pretty different. The holes are much smaller than on a Boehm flute, which really changes the response. I’m sure a differently cut embouchure would make a huge difference. As has been discussed in some other threads recently, a few people (me included) believe that the bore taper isn’t the first and foremost factor that makes a flute good for traditional music. I bet one of these could be transformed with a new lipplate, from something that’s a neat curiosity into a really interesting instrument.
