The Mk IV is here!

After extensive R&D, I’m announcing a brand new headjoint design which gives a full, round low octave and light, sweet high octave which is perfectly in tune. The polymer headjoints have been slimmed down slightly, and the bronze whistles now have additional options for alloys, including a hardenable body tube alloy which should make for great tone!

More soon - including pictures and sound samples of course.
