Serial # 00414427

The upgraded replacement for the legendary A901 series, this AWO1 brass model is suited just as well to aspiring beginners as to experienced professionals. It has a strong tonal core thanks to a re-engineered bore and toneholes, plus many upgraded features exclusive to the WO series such as newly designed Front F Keys, Ride Side Keys and Right Pinky Key.

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.

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.

TRI-POINT BRACE

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