Looks indentical in several respsects to the Kongsheng Boogieman KB-12. Same mouthpiece shape on the housing, same screwed-on metal backing plate on the front of the comb. What I can't tell from this is how the slide spring works, or the shape of the backing spring that holds the reedblock in place. Those are two areas where the KB-12 has improved on the CX-12 design
That harmonica sounds wonderful. I have an Easttop chromatic which is also quite a good harmonica, but to be honest I've got on too well with it. I've been spoiled by playing tremolo harps too much. When you get used to separate holes for blow and draw notes they seem very close together. On the rare occasions I pick up a chromatic I go for my BJ Blues harp. It's laid out like a tremolo but with a button. I am quite impressed with this one so far.
