Rims
MarkingDescription
SThe standard rim shape in the FCB line. A comfortable shape with a mild bite, excellent articulation, flexability, and endurance.
OAn "orchestral" rim shape with more (sharper) bite than the "S" rim, a "1X" style.
WSimilar to the Standard rim, but slightly wider.
PDesigned 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
MarkingDescription
7A great all around backbore.
8Consistent from low to high and soft to lound.
11A great piccolo backbore. A "117" style shape.
12A piccolo backbore that is a little more open than the 11.
