Adolphe Sax not only designed the saxophone, he also - of course - made the mouthpiece that would suit the instrument. The original mouthpiece is quite different from what later became the typical saxophone mouthpiece. The mouthpiece Adolphe Sax made is shorter and the inner dimentions are radically different having a large, almost onion-shaped chamber. In consequence the sound is different too; darker and with a very stable overtone structure.

 

Today there are a few available mouthpieces;

 

Rascher Saxophone Mouthpieces are made as exact copies of the orginal Buescher mouthpiece

 

 

Caravan Mouthpieces are in the tradition but somewhat closer to a modern mouthpiece

 

 

Original Buescher mouthpieces can often be found on eBay

There were several different models - The Mouthpiece Museum has a nice page on Buescher mouthpieces
