Hello, Slim, and Street Legal.
Thanks for discussing the 10-hole slide chromatics.
I was wrong. Please accept my apology.
I'm not familiar with the Asian 10-hole harps, but the
Hohner Chromonica (after 1928) and Hering Professional
40 are solo system, with 4 reeds per mouthpiece hole
(2 reeds per chamber).
The Hohner Koch Chromatic; Hohner Slide Harp and
Hering Vintage 40 are Richter system, with 4 reeds
per mouthpiece hole, 2 reeds per chamber.
The Hohner 10-hole Chrometta is solo system, starts
on G of the C scale. The Chrometta has 4 reeds per hole,
2 reeds per chamber.
As far as I know, Tombo & Suzuki don't make 10-hole
slide chromatics; and Seydel doesn't make no-valve
slide chromatics.
I'm unfamiliar with the modern Hohner Educator
harps, but the only antique Hohner Educator 10-
hole harp known to me is a Richter diatonic, with
appearance similar to Hohner's Golden Melody
diatonic.
Best Regards, Stay Healthy
