SummarySpecCatalogue The new Bauhaus-WALSTEIN Tenor Saxophone Deluxe Model features the same specifications and sound as the original model, the body shape and body and keywork materials are the same. The difference is the in the mechanics/ergonomics of the keywork. Bauhaus have rebuilt the action in the A.I. (Action Improved) series using a shoulderless point screw and redesigned pillar-rod mechanism. The screws are manufactured from hardened steel, and the housing mechanism is carefully engineered around them creating greater ergonomics, making for a smoother, more responsive action.
