Trumpet Cornet & Trumpet Flugel Mouthpieces

TC & TF mouthpieces are available as:

One Piece TC & TF Mouthpiece
Underpart Section TC & TF
Rim Sections

Individual pieces are compatible with other manufacturers.  Rims and underparts have Bach threads (other threadings are available as a special order).

The backbores for each cup (TC and TF) are designed to balance with each specific cup resulting in a mouthpiece that makes soft playing a snap with great sound and intonation. 

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.
TCA cornet style cup making a great hybrid mouthpiece for soft playing.
TFA flugel style cup making a warm toned hybrid mouthpiece that converts your trumpet to near flugel like in quality.
