GW-100 Tenor Trombone Mouthpiece – The Top-Selling Favorite: Pure Brilliance, Rock-Solid Stability.
Grab one of our all-time bestsellers before they're gone — the GW-100.I n the competitive world of tenor trombone playing — where players crave effortless playability, crystal-clear articulation, and a tone that's pure, brilliant, and rock-steady even at maximum volume — the GW-100 has earned its place as one of our most beloved and top-selling mouthpieces. Delivering a focused, singing tone that projects beautifully while remaining perfectly controlled and fatigue-free. Built around the classic 5G cup size for its familiar depth and warmth, the GW-100 adds a slightly larger inner rim diameter for superior comfort and flexibility across all registers — making it easy to navigate from pedal to high notes with confidence and ease. Strategic extra mass on the exterior (O.D.) locks the sound together, stabilizing it during the most extreme loud passages so the tone stays centered, brilliant, and unbreakable — no wobble, no breakup, just pure power and poise.
