Chicago French Horn Mouthpiece Cup Underpart

Designer: Osmun


Add a note to encourage purchase

The Chicago line, by Osmun Mouthpieces, is designed after the original Farkas model, a quintessential American mouthpiece. The Chicago line works well with most horns and in most bore sizes as the shape is moderately deep and less cup-shaped. The Chicago cup produces a warm timbre and very even response across the registers. They are moderately deep and with a fairly straight side it produces an even sound rich in overtones.

The Chicago line specifications:

  • .650" (16.5mm) diameter at the joint where the cup and rim meet
  • inch threads are .750-36 threads, compatible with almost all American-made screw rim mouthpieces
  • metric cups are 17.5mm at the joint where the cup and rim meet (special order 1-2 weeks)
  • metric threads are .800-36, designed specifically to be interchangeable with Osmun, Paxman and Halstead-Chidell mouthpiece rims and are offered in sizes larger than the inch models.
  • multiple shank choices to fit your horn perfectly. (European and Schmid special order 1-2 weeks)
  • bright silver plated cup (gold plated cups allow for up to 3 weeks delivery)

We carry a small number of Osmun Chicago cups in stock. Normally 1-2 week delivery for standard options. Please allow up to 3 weeks for special orders.
