    * Power swtich protudes too far.
    * The piezo volume pot is pretty ineffective, and most likely will be left at full volume. It will probably be removed in the next board spin.

    * You should use a 3.5 mm stereo cable for the key line, since the way that the key jack is currenlty wired it will not work correctly with a mono cable.
