Metric cups have PHC-compatible 800-36 threads and a 17.5m diameter at the joint. They fit our metric rims and Paxman-Halstead Chidell rims.

Our Models (listed from shallow to deep)

H (Haydn) Our shallowest cup, it’s designed to facilitate work in the upper tessitura of the instrument. Offered as stock with 16 throat. (Other sizes available as special orders.)

B (Bloom) Relatively shallow with a moderate cup shape that supports the upper register and produces a brilliant tone. Works well on 8D’s in larger throat sizes.

G (Geyer) Copy of a Carl Geyer original. It shares the essential characteristics of the Chicago cup in a shallower form.

L (London) The contour is a pronounced concave-to-convex curve. This configuration produces the vibrant tone associated with the great British virtuosi.

N (Navarro) Designed for Paul Navarro of the Chicago Lyric Opera. It combines characteristics of both London and Chicago cups.

CH (Chicago) The quintessential American mouthpiece. Modeled after the original Farkas model. Moderately deep with fairly straight sides, it produces an even timbre with complex overtones.

LD (London Deep) A bit deeper than the London cup. The increased volume enhances the low register.

CHD (Chicago Deep) A deeper version of our Chicago cup, but still with a very softly contoured wall. It’s very fluid and even in timbre.

V (Vienna) Very Deep, but with a relatively small volume due to its convex shape. Produces a dark, velvety sound that brightens when pushed.

All depths are measured to a number 12 throat.

Measurements include the rim height.

All cups are shown with Chicago rims.

The number stamped on the cup is the bore size. An M after the number indicates a metric cup.

Shanks We offer our mouthpieces in three shank sizes:

Standard: 0 Morse taper, .295” diameter; for use with most modern horns, and

Euro: 1° taper, .305” diameter; used by Alexander and some older European instruments

Other tapers (such as Jungwirth, Schmid, etc.) and sizes are available as special orders.
