Ron Wilkins Small Bore Tenor Trombone Mouthpiece – Precision Punch & Total Control
Inner Rim Diameter: .997" | Cup Depth: Medium Shallow |
This is the small-bore beast that gives you everything you need to dominate: razor-sharp control, explosive flexibility, and the kind of punch that makes sections sit up and take notice. The Ron Wilkins Signature is built for players who demand a mouthpiece that feels secure, responds instantly, and delivers power without ever feeling heavy or sluggish. With our standard .997" inner rim (perfectly balanced for comfort and focus), combined with a medium shallow cup that keeps things responsive and bright, this piece excels at giving you effortless command over the entire range. Slot into the high register with confidence, rip through fast articulations, and lay down thunderous lows — all with the clarity, snap, and dynamic range that make it a favorite for small-bore tenor trombone work.
Why this mouthpiece sizzles:
Ron Wilkins' signature mouthpiece captures the essence of small-bore mastery: control that feels effortless, flexibility that opens up endless possibilities, and punch that hits like a freight train. Whether you're leading a jazz combo, anchoring a big band, or tackling contemporary works, this is the tool that lets your sound shine with clarity, power, and attitude. Step up to the Ron Wilkins Signature — precision meets power. Control the horn. Own the stage.
