This is the first video of the newer design, which I have yet to give a name to. Until named I will refer to it as "3rd generation".
I've added notes, modified the tonal elements including scale arrangement, tapered the tongues, experimented with some strategic temperaments among other things.
The videos below this one are all of the previous model.
All orders pending and new, are receiving the newer elements which as always , are constantly improving, drum by drum.
