I think the only main difference between the two is that Yamaha has used a different brand of pads in the iii
there aint no Australian thing - far from it - as stated, its just got different brand pads (Pizoni) so i reckon it shouldn't be worthy of calling it 3rd generation, i'm not sure either.I spoke to a representative at Yamaha USA, and he stated there is no generation three 82Z in the U.S. He said the Yamaha transitioned pads to some specialty pad type on their "Custom" horns, but everything else remains the same. Is this just an Australian thing or is the U.S. just delayed in the process--I don't know.
