Wedge 665MV Hybrid Trumpet Mouthpiece

The 665MV, along with the 66MV, is the Wedge most similar to the Bach 3C. It has a cup depth that is slightly shallower than the Bach 1.5C and Bach 5C, and B7C. It therefore has a slightly brighter sound, and provides more support in the upper register than the 1.5C/5C and Wedge 665MDV.
The 665MV is a great all round mouthpiece for a wide variety of applications. The sound is a bit bright for an orchestral setting, depending on the player's natural sound and sound preferences. It is very well suited to situations where a bit more efficiency and projection is desired, such as concert band, brass quintet, marching, and jazz band.
