A professional‑grade signature Bb trumpet model—with C tuning tubing configuration (i.e. tuned to C, making it especially well-suited for orchestral/professional use). Developed in collaboration with renowned trumpet artist Eric Miyashiro, the 8330EM builds upon the legacy of Yamaha’s 8000‑series instruments while prioritizing improved high-register playability and refined control

Bell: One‑piece yellow brass bell, 134.4 mm (5¼″), featuring a French‑bead rim and side‑seam design for enhanced projection, resonance, and open vibration

Valve casing upgrades: Super‑refined valve block (first redesign in nearly two decades), incorporating phosphor bronze components (bottom caps and 3rd slide stopper) to enrich harmonic content and brightness in high register

Leadpipe & Mouthpiece Receiver: Newly engineered for balanced resistance—makes high notes more accessible and overall articulation crisper

Weight: Classified as lightweight for greater comfort during extended performance or rehearsal sessions

• The “C Trumpet” reference here refers to the instrument’s tuning setup; it retains all core performance traits of the Bb version but is configured to sound in C for orchestral compatibility.

• Ideal for advanced students and professionals seeking a refined balance of responsiveness, projection, and versatility.

• Yamaha’s professional naming convention classifies YTR-8330EM in the artist tier—falling in the top echelon in terms of build quality and playability
