Teflon octave system :
Both ends of the octave key axis rotate in a receptacle that is coated with teflon to insure a smooth operation every time
Rocking table mechanism :
The C# and Bb keys have a rocking table mechanism that allows for optimal speed and fluidity between these pitches
F-auxiliary key mechanism :
Insures a proper seal of the pads when playing in the low range of the saxophone
"Indented" white shell keys :
A player's fingers will rest comfortably in the indented white shell keys. The white shells also enhance the beauty of the instrument while also preventing the player's fingers from slipping during technical passages
Pointed pivot screw :
The pivot screws that are used have a pointed end which facilitates an accurate center and precise action
Air-tight waterproof pad :
The pads are completely air-tight which supports stability in playing and their life is extended thanks to being waterproof
Blue steel springs :
Blue steel springs give the player quick response and are much more resilient than stainless steel (they also last much longer)
Tri-point balanced bell brace :
The bell and the body of the saxophone are firm connected by a tri-point balanced bell brace
