The W-H2 is a 65 key Hayden duet, featuring the Hayden keyboard angle, key spacing, and distance between the hand rest and keyboard.
The instrument is also available with the Wicki keyboard. This instrument (W-W2) has identical specifications, but with the keyboard running parallel to the handrest.
The W-H2 features our long scale tapered (instead of parallel) steel reeds in MS57 brass frames. Tapered reeds provide excellent reed responds at low airflow, a wide dynamic range, and uniform harmonic equilibrium.

The standard W-H2 model has French polished walnut, Padouk, Maple, or Ebonized flat ends. Raised ends and other types of wood are optional.
