Being able to hear each of the unique sounds of the different sizes of the didgeridoos was super helpful , and that buying a starter pack was priced so competitively made buying from Sanshi and team a no brainier , getting an authentic didgeridoo was very important and these guys delivered , I am an aboliste beginner and the included lessons are turning out to be incredibly valuable as well !! I am already planning on buying a small box didgeridoo for travel and a larger didgeridoo for a different sound :)
