All the best with Chromonica 280 c. It’s a vintage instrument that will remain unsurpassed. 
… I also play Tower Chromatic in 24 hole, Tombo Uni Chromatic in 12 hole, Suzuki Songstar in 24 hole, Suzuki Chromatix in 16 hole, Hohner 280 c Chromonica in 16 hole, Höhner Meisterklasse in 14 hole & Hering Chromatic Deluxe in 16 hole… But Hohner chromonica sound 
is Vintage like no other Chromatic Harmonica… Because it’s a 1938 invention. What I do is listen to the Pre 1920s, 30s and 40s born Harmonica legend’s on Chromatic and also Diatonic… Because it helps me to improve and improvise my own pattern. The Real joy of playing any music instrument’s is to duet and play with another willing person in harmony… I don’t play on stage with gear, gadgets and accessories and neither in public… I play to enjoy at home or in the Forest during pleasant climate…
Enjoy Your ongoing Practice…
