The 3DR, or Triple Didge Rack, is Andy Graham's first music-related invention. Built in 1996, the 3DR is what allowed Andy to
begin experimenting with simultaneous drum and didgeridoo playing, which later led to his solo performances. Build of rugged stainless
steel, the 3DR has survived many years of abuse without any complaints. Even so, in 2005, Andy decided to 'beef-up' the system by
adding stronger 3/8-inch bronze tensioner rods with slick oval-shaped handles.
