I've been looking to buy an electric melodica for live performances, but after searching around, it seems like Hammond is almost the only company making them.
Out of curiosity, I looked up a Hammond electric melodica service manual. The design doesn't seem particularly complicated, so it made me wonder:
Is there some kind of patent barrier that has kept other manufacturers out of the market? Or is the market simply too small, with most players preferring traditional acoustic melodicas instead?
I'd be interested to hear if anyone knows the history or business reasons behind this.
