Recently I bought a new (expensive) didgeridoo and am very happy with it. But I have a problem with it. With my normal cheap didgeridoo's I can do the basic drone without any problem but with this one I am trying and trying and in the end after much effort it is starting. Once it starts then it takes some time but after that I can play it like my normal other didgeroo's. Does somebody recognise this? Any tips? Thanks!
