TUBA IN C THUNDERBIRD 6/4 48cm bell - Silver-plated

The Thunderbird 6/4 ZO B-flat Tuba is a professional model designed to deliver a powerful, balanced sound with broad projection, inspired by the legendary Chicago York instruments. Its large bore body and 6/4 design allow for a solid, stable low register with the necessary breadth for large symphonic ensembles.

The 48 cm bell provides clear and expansive projection, while the silver-plated finish over yellow brass adds durability and a brighter, more defined acoustic response. The combination of 4 front stainless steel pistons along with the 5th rotary valve ensures precise tuning, reliable mechanics, and comfortable fingering even in complex passages.

The progressive bore of 19.4 to 21 mm is designed to provide a homogeneous air column, favoring tonal stability and allowing for fine control of the sound emission. With a height of 93 cm and a weight of 12.3 kg, the Thunderbird 6/4 achieves a balance between resonant mass and maneuverability.
