It was around summer 1998 when I first heard a friend of mine play a self made didgeridoo. I was mightily fascinated by the sounds you could get out of a simple pipe-like thing. So I went to build my own, since buying a new and original one was way out of my financial possibilities at that time. After a month of practice, I learned to do circular breathing, and the rest is history.
These are the instruments I acquired over time. The different materials do produce a quite different sound. I personally love the crystal-alike sound of the glass didge.
