The YAMAHA YTR-8330EM Bb Trumpet, developed in close collaboration with the famous Japanese jazzman Eric Miyashiro, provides a powerful and dynamic sound. Featuring a wide bell with a flat rim, it ensures optimal sound feedback to the musician. The tuning slides and the pinky hook are equipped with rings for perfect grip and enhanced playing comfort. The unique brace design improves tactile response and facilitates tuning.

Manufactured in Japan, this trumpet is part of the Eric Miyashiro Custom series. Its large multi-bore and 5.3-inch (134.4 mm) flat-rim brass bell contribute to its distinctive tone. The Monel pistons ensure smooth and durable action. The gold lacquer finish adds a touch of elegance, and the TR-EM1 mouthpiece and included case complete the package.

Among its advantages, the precise Yamaha tuning provides impeccable intonation and balance. This trumpet is particularly suited for various musical styles, making it a rare find in the market. Its impressive sound width and efficient performance, along with its lighter weight, offer a more imposing tone and optimal sound projection.

However, some aspects can be improved. While the tone has been enhanced, it may still sound slightly flat in some cases. Additionally, the instrument's aging capability can vary. The provided case is considered impractical by some musicians. Finally, the leadpipe design may be perceived as imprecise by certain players due to its unconventional design.
