Denis Wick - 4880E-SM4X Ultra euphonium plaquée or SM4X

The Denis Wick 4880E-SM4X Ultra euphonium mouthpiece is a gold-plated model developed in the Steven Mead Ultra series. It features a more solid external shape, designed to improve sound projection and density. This design gives an immediate feeling of solidity under the lips.

The 26.00 mm bowl diameter provides an effective balance between fullness and control. The 6.3 mm rim width contributes to a comfortable fit during long playing sessions. Its 7.40 mm bore facilitates smooth, even airflow. The internal profile combines funnel and bowl characteristics. This blend promotes a rich, centred timbre, typical of the modern euphonium sound.

The response remains stable even when the instrument is under heavy load. The Ultra X version provides even greater support in the demanding passages of the upper register. Attacks become sharper without losing roundness. The sound retains its depth while gaining in clarity. The Wide Tail with V-Type backbore ensures even distribution throughout the entire range.

This model is just as suitable for solo playing as it is for orchestral or wind band sections. It is ideal for instrumentalists seeking a precise balance between comfort, projection and sound control.
