The YTR-4435ll is a convertible type with extra slides Bb to C.
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 yellow 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.
