Chuck Findley 66MV Hybrid Trumpet Mouthpiece

The Chuck Findley 66MV plays like a really great 3C, but with a very slightly smaller diameter.
The 66MV is the most popular mouthpiece wedge sells, simply because it works well for many players in many playing situations. This size is the "multitool" of mouthpieces as it is best suited for playing in concert band, wind ensemble, brass quintet, worship groups, jazz, pit and pops settings, and almost anywhere else.
Although not a typical choice for an orchestral setting or for playing lead, the 66MV can also be made to work for that type of playing. Keep in mind that this particular "C" cup is not quite as deep as the Bach 1-1/2C, 5C, or 7C cup. It is the most shallow of all Bach C cups
