Big  OMTBA400 3/4 Bb Tuba

The O’Malley Bb Tuba features 4 rotary valves.  The rotary valves work cleanly and smoothly thanks to the miniball linkage.  You will be asking yourself why this is considered a 3/4 size.  This horn plays with a big full rich tone thanks to the .787 bore and the 14.7 inch bell.  This horn romps in all registers from booming and powerful lows to singing and full bodied upper register notes.  It blows clean and open that makes it easy to play even for the youngest players.  And the size makes it comfortable for students from middle school to high school and beyond.

The O’Malley3/4 Tuba is constructed with Yellow Brass and is available in lacquer or silver finish.  The tuning slides are strong and durable because of the nickel inner and outer construction.  Why should middle students be relegated to playing old beat up high school hand me down sousaphones or tired old 3 piston valve tubas when you can afford to outfit your entire section in a big sounding  professional 3/4 size tubas?   Compares to the John Packer Sterling professional 3/4 tuba.

The O’Malley 3/4 Tuba comes with a mouthpiece and a Foam Body zippered case.  The case has wheels on the back to allow for pull behind carrying.
