Contra bass trombone Mouthpiece

This is the contra bass trombone dominator designed for Bob Sanders, the legendary LA low-brass titan (Hollywood session legend on films like Planet of the Apes, Avatar, X-Men, and countless soundtracks; former Disneyland Band to Pacific Symphony powerhouse; the guy who made contras roar in the Garage Band era with Tommy Johnson and Phil Teele).

Bob's mouthpiece is engineered to lay orchestras to waste, flatten horizons, and rattle internal organs with pure, controlled low-end fury — all while staying balanced, playable, and not overly massive. We crafted it specifically for Bob's contra bass needs: a perfectly sized rim and cup that covers every aspect of the instrument — deep foundational rumble, cinematic projection, and that signature "Brassy Grit" Hollywood composers crave — without ballooning into something unwieldy. Projection is effortless (cuts through massive brass sections like a hot knife), articulations snap fast and crystal-clear (no mud in the low depths), and the expansive yet controlled sound delivers robust power that's dark, focused, and authoritative.

Why this mouthpiece dominates:

• Balanced & versatile — Handles everything from orchestral depth to soundtrack intensity without being "too large" — ideal for pros who need control in the abyss
• Explosive projection — Throws massive, brassy tone across halls or studios with ease
• Fast, precise articulation — Clean attacks and quick response even in the pedal register — perfect for rhythmic drive or dramatic swells
• Signature "Brassy Grit" — The raw, edgy character that makes contras shine in film scores, opera pits, and epic orchestrations — bold without being overblown
• Comfortable & efficient — Stainless steel transfers your air with maximum power and endurance, hypoallergenic, and built for marathon sessions

Bob Sanders — retired now but still the stuff of low-brass legend — knows what it takes to make contras thunder in the biggest rooms. This mouthpiece is his ultimate dominating mouthpiece of choice: a beast that moves air, shakes rooms, and leaves audiences stunned — all with the musicality and control that defines his career. When the score calls for earth-shaking lows that command respect, grab the Bob Sanders Contra Bass. Horizons flattened. Game over.
