Rick- I haven't really experimented with the Oskar or Huang harps. I saw some Oskar harps which had replaceable reed boards, which I thought was a great idea, since I only get about a years worth out of a harp before the reeds or the cover plates are shot.I've used Hohner's Marine Band and blues models, but the Marine bands have a more clean harmonic that doesn't work well for the blues, though I think it would be great for folk music, Dylan-style.I have worked with the Chromatics, but that requires true musicianship which, I'm afraid, I lack.
