Finer quality brass is used by manufacturers in the production of upgrade saxophones.  

Metal finish options like black nickel and lacquered brass allow for a custom look and sound. 

Double-braced keys help provide stability and even pressure on the key cups, ensuring a more consistent seal on the pads.

The neck of a saxophone has a major impact on the sound and feel of the instrument. Upgrade saxes feature a neck that is often hand-finished for improved intonation, response, projection, dynamic range, tonal feel, and sound color.
