Who the Bach Classic 3CWGP Flugelhorn Mouthpiece is For
The Bach 3423CWGP Classic 3CW is a medium-cup flugelhorn mouthpiece intended for players who need a versatile, centered setup for ensemble, studio, and solo work. The 16.30mm cup diameter and medium cup profile balance comfort and control with the flugelhorn’s warm, blending sound, making it a practical choice for serious students, working musicians, and professionals.
