The Yamaha professional tuba lineup is growing with the brand-new addition of the YCB-623 Series CC tubas. Designed with input from world-class tubists, like the legendary Jim Self, these York-style, front action piston tubas were tested for years in orchestra halls, iconic Hollywood studios, and university band rooms. The YCB-623 series offers a powerful core of sound across all registers, beautiful resonance, rock-solid intonation, and renowned Yamaha action to create an energetic and reliable foundation for their ensemble.
