We almost don't have room to list all of the advantages of this instrument. Perhaps its best feature is the fact that it can be dismantled down to 4 pieces in under 10 seconds with your bare hands! That's right, no more major repair jobs just to remove a piece of food caught in a reed. The innovative design includes a plastic one piece outer shell that serves as a mouthpiece and cover plates all in one. The shell acts like a megaphone, amplifying the CX-12's sound, making it one of the richest, loudest sounding harmonicas on the market. The button action is smooth and fast, and it's easy to fix when it isn't working properly. The all plastic construction (except for reeds, reed plates, and slide) makes the CX-12 the most rust resistant chromatic available, and one of the most durable. The shell offers a super smooth playing surface for speedy, comfortable movement up and down the instrument. Durability, easy repair, great sound, airtight responsiveness, comfortable playability...what more do we look for in a chromatic? Notice that we offer the TENOR C as a key choice which is one full octave lower than the regular C...talk about rich!
