I had aspirations of learning the chromatic harmonica, but it was just never meant to be. I have two instruments for sale - both at great prices for what you get - you'd just want to soak the combs/reeds in white vinegar if you are concerned about them being squeaky clean. But I hardly ever play them, and that is why they are for sale.
Suzuki Chromatix 48 ($150)
This one I have priced at half off of the price of it new. It is the standard chromatic tuning in C with three octaves.

Kongsheng Lyra 12-Hole 48 ($100)
This one should be listed as "Like New." It is an orchestra tuning meaning it is still 12-hole, but two holes have been added to the low end, and the two high holes have been removed (so it goes a little lower than a standard tuning but not as high). Also in the key of C. These are sold new for $159.

I'll give you a discount if you want both of them.
All notes are clean and reeds are in 100% working order.
