Kind of neat idea, trying to make the perfect horn; vintage sound with the modern Mark VI keywork.Dave Kessler just posted these links on facebook:
These horns have soldered rim rolled tone holes ala Keilwerth.
If my "Intermediate" Kessler Deluxe Tenor is an example of the quality of these new models, I suspect them to be monster players.
I'll be interested to see what people say about them when they come out.
By the way, I have a Kessler Custom Alto, paid $700. I also have a Pan Am alto, similar to a Conn 6M, paid $175 for it. That's a monster player. Kessler is not, sorry.
