The Hohner Harmonetta (out of production) is quite an interesting and mechanically complex instrument.
Inside the shrouding is a complex web of buttons, rods, cams, and springs. Underneath all of that, is a comb with 36 chambers and reed plates with 72 reeds. Each chamber contains two reeds (blow and draw) which are the same pitch. Of course, this makes wind savers necessary.
The Harmonetta is a fantastic sounding instrument. When the wind savers get old, they harden and flutter.
I have just completed my first resurrection of a Hohner Harmonetta. It is said to have once been owned by Don Les. When I received it, many screws were missing and the shroud was held together with three large rubber bands. Since the original screws are no longer available from Hohner, I reassembled the instrument using SAE replacement screws. The instrument is back together and sounds fantastic once again!
So it with this that I am adding Harmonetta Repair to my menu of services.
