The CX-12 is the chromatic that sounds most like a diatonic, for two reasons:
1) It's very loud and responds well to a hard attack.
2) It bends farther and more easily than most chromatics, right out of the box.
No chromatic sounds exactly like a diatonic (just as no diatonic sounds exactly like a chromatic). But an amped-up CX-12 can give you a similar vibe.
