    >>> The Koch 10 hole chromatic which is Marine Band (or Richter) tuned.
    i.e., tuned like a blues harp in the first three and last three holes. See
    diagram below.

     (SLIDE IN - NOT SHOWN - RAISES ALL NOTES 1/2 STEP GIVING YOU A C# HARP)

        The KOCH chromatic harmonica is tuned just like the diatonic, thus you
    get a bit of the bluesy sound, at least you can play cross harp and get
    the "G" chord etc. - but not the power or sound. It is available in C and
    G, I don't know about other keys. Oh, BTW, it is sold by Hohner. If you
    hold the button in you have a C# (Db) harp.
        I personally don't recommend this harp for those just learning to play
    chromatic - it can really screw you up (I had a student show up with one
    in my chromatic class once and it took an hour to figure out why he
    couldn't get the C scale starting on hole #1). It is well constructed and
    durable but lacking in power mainly because they didn't bother to put
    valves (windsavers) on it - a must for chromatic harps. Addition of valves
    would make it a decent instrument. What do you do with it? Well you can
    play it like a blues harp (cross harp) - it bends O.K. and by using the
    slide you can get notes you would normally have to master overblowing to
    get. I have one in G and will probably never use it much until I get
    around to putting valves on it.
