Rims
Marking Description
S The standard rim shape in the FCB line. A comfortable shape with a mild bite, excellent articulation, flexability, and endurance.
O An "orchestral" rim shape with more (sharper) bite than the "S" rim, a "1X" style.
W Similar to the Standard rim, but slightly wider.
P Designed for use with the "P" cup for piccolo. A comfortable and broad shape that aids the upper register. It also works great as a lead rim.
Cups
Marking Description
D A deep cup, very dark on trumpet, great for cornet.
MD A deep B cup with a "deepened C shape" and not a "V" shape. Great on rotary or as a deeper orchestral cup.
5B A B type cup based on a Mt Vernon 5B. This is popular with 1 to 1 1/2 size rims for orchestral/classical playing.
MVD A traditional "C" type cup shape based on a Bach Mt Vernon 1 1/4C cup. This is the most popular orchestral cup.
MV A traditional "C" type cup shape great for all-around playing.
MC An efficient cup with a quick response and vibrant sound. Described by clients as a super charged 3C cup, it has a steeper initial slope with a flatter bowl.
M Shallower than MC cup and versatile; a shallow "C" type cup.
MS A shallower version of the M cup, a "D" type cup; facilitates a lighter sound, and easier upper register.
S A very shallow and flat "E" type cup.
P Designed to work with the "P" rim for use on piccolo and for lead. More of a "V" shape than the M cup.
Backbores
Marking Description
1 A compact and "tight" lead backbore, works best with shallow and compact diameter cups.
2 A compact lead backbore, with surprising versatility. Works best with shallow and compact diameter cups.
3 A versatile backbore with resistance for lead, yet is useful in a variety of situations.
5 A great commercial, lead backbore, or even all around backbore. A "76" style shape. Most classical players looking for a pops type mouthpiece like this backbore.
6 A dark sounding backbore with great articulation. A "7" style shape.
7 A compact "24" style shape that has less second flare to the taper.
MTV The most popular Bb trumpet backbore, a copy from an outstanding Mt. Vernon 1C backbore.
8 A very consistent backbore - soft to loud and low to high, a "10" style shape.
9 A "57" style shape with a warm and broad sound. Works well on rotary trumpets.
10 The standard orchestral "24" style shape, it has more flare in the second taper than the #7 - larger total volume. The most popular C trumpet backbore.
11 A great piccolo backbore. Some like this backbore for orchestral work, it stays warm when played loud, sounds big. A "117" style shape.
12 A dark backbore that is also large, a "D" style shape.
