Also the timbre or tonal characteristics of that alternate F# fingering are seldom exactly the same as the regular fingering on most saxophones. As was mentioned, if the note is excessively stuffy, the key can be opened a bit by sanding the cork on the foot of the key where it contacts the saxophone. You can do this yourself with an emery board, but it is very important that you cover one side of the board with masking tape so that you do not scratch the body of the saxophone if you sand the cork with the key on the instrument. Opening the key beyond 1/3 the diameter of the tonehole will not change the pitch or tone quality.
