YCR-4330GII Bb Cornets
Pistons, piston caps and buttons
Highly durable monel alloy pistons as well as piston buttons and bottom caps help lengthen the life of the instrument while also maximizing sound quality.
The 2nd and main tuning slides are produced using the same method as high-end Yamaha models, which provides stability, a more refined tonal color and added durability.
Bore size and lead pipe
The redesigned rounded leadpipe and ML (medium-large) 11.65mm (0.459") bore give this instrument a smooth and light response and a warm tone quality.
