BEST BRASS Groove Series 5C
Gold Plated Finish

Comes with original box.
Excellent condition, only tested.

The Groove Series mouthpiece features a fine groove-like structure called Groove in a portion of the throat.
The Groove generates moderate blowing resistance (back pressure) that allows the lips to vibrate easily, aiding in natural and efficient lip vibration.
This new invention has achieved overwhelming relief from lip fatigue, expanded the playable range, and produced a powerful tone compared to conventional products.
The most noticeable feature is the ability to stably produce high and low notes that were previously difficult to reach.

Numerous other innovative ideas have been incorporated, resulting in a groundbreaking mouthpiece unlike any other.

[Throat for Advanced Players]
Designed for advanced players, the throat size is slightly larger than standard. Additionally, the Groove technology provides beneficial blowing resistance (back pressure) that allows for easy lip vibration despite the larger throat, enabling maximum volume with minimal effort.

[Backbore Designed for Sound Balance]
The complex taper, carefully considering sound pressure distribution, achieves the best balance by considering the interplay between the cup, throat, and instrument.

[Luxurious Gold Plated Finish]
All mouthpieces are finished with pure gold plating over a thick layer of pure silver plating. The extremely smooth rim feel facilitates lip control, producing a rich and resonant tone.
