I also have a white elephant D/G Erica. I started to follow Mally's beginner course but I missed those low notes that aren't there for some Irish tunes (I know I could get that fixed). In addition, and far more seriously, as a harmonica player I found I was breathing in and out as if I were playing the notes on the harmonica. In spite of huge efforts to resist this I couldn't overcome it. I also found that my bellows "technique" was lugubrious and clumsy in the extreme. I might have another go some time.
