Common Questions About the Willson Q90S
How does the Q90S differ from the standard Q90?
The Q90S is the silver-plated version of the Q90. It retains the Q90's Bb compensating system, 0.590-inch bore, 11.5-inch one-piece yellow brass bell, and 3+1 piston configuration.
What does the compensating system contribute?
The compensating system adds supplementary tubing when lower valve combinations are used, helping improve intonation and fingering flexibility in the euphonium's low register.
What mouthpiece format does the Q90S use?
The Q90S uses a large-shank receiver. This instrument includes a Laskey 59D mouthpiece.
