Evolution of the palm keys
We’ve refined the ergonomics of the left-hand palm keys. Angling the key touches more toward the bell affords more control.
Evolution of the high-G and high-F# keys
The orientation and shape of the key touches for the high-G and high-F# keys have been improved to facilitate smoother operation (on interchangeable models only).
Evolution of the low C/D# key spatulas
The right-hand key spatulas for low C and D# have been moved forward for easier reach and improved action by the little finger.
Evolution of the G hinge rod
Nickel-silver has replaced brass as the material for the G hinge rod on the upper stack. As a harder alloy, it adds strength and durability while helping the mechanism stay in good adjustment.
Evolution of the neckpiece
The neckpiece on interchangeable models is reinforced with a trapezoidal plate that delivers a nice sense of resistance with tonal colors that boast more depth.
