The YAMAHA YSL 446 GE II Full Trombone is a high-quality instrument, manufactured in China. Its 0.525 inch (13.34 mm) ML bore provides remarkable ease of play, perfect for beginners and students. Its bell, made of rose brass, measures 8.44 inches (214.4 mm) in diameter, lending an elegant aesthetic and a soft sound quality.

The nickel-silver slide ensures smooth playability and precise adjustments for perfect intonation. The lacquered finish offers lasting protection for the instrument.

The included case provides secure transportation, although its design could be improved.

While the YSL 446 GE II boasts adequate mechanics and finish, its sound projection is somewhat limited, which may affect its presence in group performances. Its tone can appear flat and lack a distinctive sonic identity.

It should be noted that the trombone's barrel can be delicate, especially the string links. Careful handling is recommended to avoid any damage.
