Wedge 665MDV Hybrid Trumpet Mouthpiece

Bach's sizing between the 1.5C and 5C has always had a gap — and the 3C, while it fills the diameter range, has a shallower cup that changes the character of the sound. The Wedge 665MDV was designed to address that specific problem: an inner diameter similar to a Bach 3C, with a cup depth closer to the 1.5C and 5C. For players who love the sound of the 1.5C but want a slightly smaller, more efficient rim diameter, this is the model to try.

The Hybrid version pairs the Wedge's curved, oval rim design with a 3D-printed polymer rim and cup liner made from medical-grade resin — permanently bonded to a brass base. The rim is warm and comfortable on the lips, especially over long playing sessions, and the oval shape is designed to follow the natural geometry of the embouchure rather than work against it.

The Wedge rim reduces pressure on the corners of the lips — the area most associated with fatigue and injury on conventional mouthpieces — while the elliptical cup shape provides smooth, even airflow from the player's lips into the instrument. You play it like any other mouthpiece, but with less interference between the equipment and your embouchure.

Comparable in feel and character to the Bach 1.5C, 5C, and 7C, as well as the Monette B3, Schilke 15, Warburton 4DM and 4D, and Yamaha 16C4.
