• Eastern Music Flagship Model: This is our premier 4-piston BBb tuba, engineered for the professional orchestral musician who demands nothing less than exceptional tone, intonation, and response.

• Massive 442mm Bell: The oversized bell delivers a wall of sound – dark, rich, and incredibly projecting. Your sound will effortlessly fill the largest concert halls and outdoor venues with authority and warmth.

• Tapered Bore Design (18.5–19.5mm / 0.728–0.768″): The progressive bore design offers the perfect balance – narrow enough at the leadpipe for precise control and quick response, widening to 19.5mm for free-blowing ease and massive volume when you need it.

• Premium Material Configuration:

  • Yellow brass leadpipe – delivers a bright, focused core with excellent projection and clarity.

  • Phosphor copper tuning slide – enhances harmonic richness and overtones, giving your sound extra warmth and complexity while resisting corrosion.

  • Stainless steel pistons – ultra-smooth, lightning-fast action with zero friction. Stainless steel is virtually immune to wear and corrosion, ensuring your pistons perform like new for decades.

• 4-Piston Full Chromatic Range: The 4th piston unlocks the complete low register, giving you access to pedal tones and extended low notes with rock-solid intonation – essential for advanced orchestral and solo repertoire.

• Professional Gold Lacquer Finish: The high-gloss gold lacquer not only gives a stunning, stage-ready appearance but also enhances the instrument’s natural resonance and protects the brass for a lifetime of performance.
