Though the wording of the ad itself is a little strange in the beginning, there is no denying that the Contrabass Saxophone that it lists is a unique find for a musician or a collector. The sax was custom built in 2001 - before the instruments entered a very limited, but regular, production - and has been used professionally since. The Contrabass is the lowest playing real saxophone in the world, handcrafted in Italy by Orsi, and there are so few that it is rare that one comes on the market at all. It is 6'4" tall and weighs about 45-lbs. Two cases are included, a "lightweight" traveling case and a very sturdy shipping case that is about the size of a refrigerator (with wheels). Price: $22,500. Be sure to check out the music clips on the sale site to hear what it sounds like.
