Keeping the same basic design of the hugely successful YTR-4335G, the new version offers some real improvements in terms of playability and a more powerful sound. The 4000 series now comes with a modified two-piece gold brass bell with a thickness of metal that has improved both sound and playability. Newly designed heavier valve caps and buttons give the trumpet more projection and power.
- The newly redesigned, durable yet light two-piece bell is made of gold brass for a wide range of tone colors and to promote good technique and endurance.
- Highly durable monel alloy pistons as well as newly designed 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 colour and added durability.
- Main tuning brace lets sound more focus and hold together.
