Slightly off topic , but a question about the hohner 114 C:

What´s the reason for its closed key mechanism?

I don't know why they do it like that. Maybe it is one of those "that's the way we have always done it" kind of things. When I bought mine, the very first thing I changed was to remove the cover, and covered the flappers with gold mylar tape.

I also removed the cover and tried to cover the flappers with tape, but that didn´t work [:-|.

I think I´ll paint the flappers black. If that does not work I can fix the cover again
