The O’Malley  Compensating Euphonium

is designed and constructed in a manner that compares to the great instruments manufactured by Besson years ago.  The valves on the compensating Euphonium are longer and consists or additional paths for the air to pass in order to achieve the best possible intonation with the least change to the tone of the pitch.  The O’Malley 1150S Euphonium plays with a rich, beautiful tone.  The bottom end of the instrument sounds with a big robust sound and the middle range blends effortlessly into the upper register.  The horn blows easy and lyrical passages are executed flawlessly.

The Compensating Euphonium1150S  has a primary bore of .590.  The secondary bore of .661 is in place when the 4th valve is used.  The dual bore nature contributes to the evenness of tone and great intonation when playing passages that cover a broad range of the instrument.  The conical bore of this Euphonium ends at the 11.5 inch bell.  The bell and lead pipe are constructed with a sturdy yellow brass.  The piston valves are smooth and quick in execution of the most complicated and technical passages.  The O’Malley 1150S is equipped with a large shank mouthpiece receiver.  This instrument comes in a silver finish with gold trim package.
