The side F key is operated from the front, expanding the ability to produce the flageolet sound. The opening of the F key is able to be adjusted individually, so that the optimum point can be easily found.
Forefinger control of the Palm-F key broadens the range of the possibilities for altissimo harmonics. The ideal setting is possible because this mechanism allows the opening of the high-F key pad to be adjusted independently.
Adjustable vibration-damping bar
This enhancement dampens sympathetic vibrations in the right-hand F# key, thus stabilizing the production of notes in the lower register.
The teflon inner octave system
Both the ends of the octave key axis are in a ball shape and teflon is inserted in both receptacles of the ends to eliminate any looseness and ensure smooth operation.
C#-Bb connected table key
The C# key and Bb key have adopted a seesaw system to make a speedy but smooth finger travelling possible.
C#-Bb table key linkage
The seesaw linkage between the C# and Bb table keys fabricates faster, smoother fingering technique.
C#-Bb & C#-B double connected table key
C# - Bb keys are connected with a seesaw system between the C# - B, and a smooth connected motion has been achieved as a unique system of our own.
C#-B table key linkage
The additional slider mechanism between the C# and B table keys is a special design that allows smoother finger transition between these notes.
Round surface octave key
The surface of the octave key has been rounded to fit the finger shape and movement to achieve a smooth touch.
One key column long seat
Functioning in favor of the shock-proof nature of the pipe.
Goldplated thumb hook & rest
Mounted with only four small points actually making contact with the body, the thumb hook has virtually no effect on the resonance of the instrument and the thumb rest, made of brass, permits a more consistent tonal range.
Metal thumb hook and rest
Designed to make minimum point contract with the body, the thumb hook enables the instrument to resonate more freely while the brass thumb rest allows for smoother response and improved tonal balance.
Pointed pivot screw
A precise and highly reliable pointed pivot screw is employed. Maintains center arms steady and achieves a very high precision action.
For the utmost in precision and reliability, pointed pivot screw ensure that center arms or hinge rods are an exact fit.
Air tight waterproof pad
Completely air-tight pad allows a stable playing without loss of breath. Waterproof Pad extends its life.
Airtight pads facilitate balanced, leak-free while quality water-proofing extends pads service life.
Metal reflectors make the tone clear and give an excellent playing response from pianissimo to fortissimo.
Metal tone boosters
Pads equipped with metal tone boosters enhance tonal clarity and ensure excellent response at any volume, from pianissimo to fortissimo.
Steel spring is more resilient than stainless. Quick on the startup, it accommodates the highly dexterous playing needed for difficult passages.
Blue steel needle springs are more elastic than the stainless-steel variety, offer faster action and render a better command of difficult passages.
Double arm key
Two separate arms combine their strength to prevent twisting or distortion of the cup. Durability is also improved.
Dural arms prevent larger key cups from twisting and flexing under pressure and also improve durability.
Tri-point balanced bell brace
The bell and the body are firmly positioned by a tri-point balanced brace to achieve a strong resilience that ensures a firm resonance even when fortissimo is sought.
The tri-point bell-bow brace ensures structural stability and rigidity and enhances resonance even a fortissimo levels.
Genuine mother-of-pearl touches
Indented mother-of-pearl key touches are attractive, afford the fingertips a more natural fit and feel, and less slippery than plastic touches when wet.
Palm key reinforcement plate; Integrated post-rib construction
Primarily intended to add strength to soldered interface between key post and the body, the palm key reinforcement plate and stack post ribs also protect body from damage should a post receive an accidental blow. They also add mid-range resonance, acoustic depth and projection across all registers, and exceptional tonal stability.
