I also seem to get lots of problems with the 2 hole draw and bend in a new harp. I was beginning to wonder if I had broken a new special 20 in C. I can bend and draw the same hole in an A special 20 fine. Now I am just a beginner on harp but I am a blues pianist so I had been practising my draws against a keyboard to see where I was at in terms of semitones to improve my notes and ear. Have I bust it? If so can I tell by removing the covers. Can I fix it ie is it the air gap. I used to restore harmoniums and they are just giant mouth organ really. I know I could well bust it but I only have myself to blame.
Any advice welcome.
Great videos by the way but couldnt find any jam tracks.
