Yanagisawa's traditional brass model, the T-WO10 has earned high marks for mechanical reliability and a tight tonal core with great projection. It has many important features for the serious player including:

Fluororesin-sleeved octave rocker
Lost motion is eliminated and smooth octave-key action is ensured by rounding the octave rocker ends and Fluororesin-coating the receiving sleeves they contact.

C#-Bb table key linkages
The seesaw linkage between the C# and Bb table keys facilitates faster, smoother fingering technique.

C#-B table key linkages
The additional slider mechanism between the C# and B table keys is a proprietary Yanagisawa design that allows smoother finger transitions between these notes.

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.

Genuine mother-of-pearl touches
Indented mother-of-pearl key touches are attractive, afford the fingertips a more natural fit and feel, and are less slippery than plastic touches when wet.

Metal thumb hook & rest
Designed to make minimal point contact 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 screws
For the utmost in precision and reliability, pointed pivot screws ensure that center arms or hinge rods are an exact fit.

Sealed, waterproof pads
Airtight pads facilitate balanced, leak-free play while quality waterproofing extends pad service life.

Needle springs
Blued-steel needle springs are more elastic than the stainless-steel variety, offer faster action and render a better command of difficult passages.

Double-arm keys
Dual arms prevent larger key cups from twisting or flexing under pressure and also improve durability.

Tri-point brace
The tri-point bell-bow brace ensures structural stability and rigidity and enhances resonance even at fortissimo levels.
