Long-term consistency of touch can only be achieved through an intelligent design approach that embraces the most advanced methods and materials.
Made from a custom mold, die-cast parts are formed exactly the same every time. The GL Series Grand Pianos feature a minimum of five aluminum action brackets that are die-cast to provide an added measure of strength and uniform stability for accurate touch over time.
Both the hammer rail and the wippen rail are permanently locked in place to preserve the exacting tolerances of the action design and ensure consistent touch over the life of the piano.
GL Series hammer rails are made of durable extruded aluminum with our exclusive Dual-Beam design for strength and stability.
The entire surface of the hammer rail is finely serrated to hold hammer flanges securely in place for optimum hammer alignment and a more precise hammer strike.
The Insuliner stretches across the full length of the hammer rail. It absorbs excess vibrations to reduce action noise and seats the hammer flanges in place to preserve optimum hammer alignment.
Finely-threaded machine screws fasten more securely to the rail than the conventional self-tapping sheet metal screws used by other piano makers. Lock washers and pre-threaded rails further ensure that screws stay tightly fastened and hammers remain properly aligned for long-term precision.
GL Series hammer shanks are reinforced on both sides with strong, rigid phenolic material. Positioned at the “fork” where the hammer shank experiences the greatest torque, these stabilizers reduce flex and side-to-side movement that can diminish the accuracy of the hammer strike.
Longer keys make playing easier and provide more even response from the front to the back of the playing surface. A taller profile and concert length maple key buttons add rigidity for increased energy transfer and greater power.
ABS-Carbon action parts infused with carbon fiber are many times stronger than wood and virtually impervious to shrinking and swelling due to changes in humidity. This extraordinary combination of strength and stability allows ABS-Carbon parts to transfer energy to the hammers with unparalleled efficiency, power, precision and nuance for a superb playing experience that will last over time better than any other piano.
This pivotal link between the key and the hammer is made of carbon and polyacetal rather than wood. Its superior one-piece construction and patented “Tapered Core” design make the Carbon Jack stronger and more reliable than any conventional wooden jack. The microscopic surface texture at the point where it meets the hammer dramatically increases control during pianissimo passages. Because it is virtually indestructible, does not warp due to humidity, and requires no lubrication, the Carbon Jack is an essential element of stable, consistent touch.
