6A4A Hybrid Traditional Top

The Wedge Hybrid consists of a 3D printed polymer rim and cup liner permanently bonded to a brass base.

The rim and cup liner is made from a safe, medical grade resin used in the dental profession to print permanent crowns. It is composed of 51% nano-ceramic particles, which gives it characteristics very similar to natural tooth material, or bone. The material is certified as non allergenic, non irritating, and safe for prolonged skin and lip contact. 

Advantages of the Hybrid design compared to other materials, including an acrylic top on a brass backbore:

* Avoids allergic reactions to metal mouthpieces - no contact with metal on the rim OR cup (unlike plastic screw rims).

* Feels warm, like other plastic mouthpieces.

* Smoother and more comfortable than gold or silver plated brass.

* Slightly more grip than silver, providing better endurance - less grippy than acrylic.

* Provides a slightly warmer sound than brass.

* Notes lock in, or slot better than acrylic, very much like brass.

* More core and clarity in the sound than acrylic.

* Clearer articulation than acrylic.

* Better feedback to the player than acrylic - feedback and connection to the horn feels like a brass mouthpiece.

* More durable and very resistant to breakage, unlike acrylic.

The 6A4A HT provides excellent brilliance, projection, and slotting in extreme upper register playing. 

The Schilke 6A4A and similar mouthpieces have a long history as very effective small diameter, extra shallow lead mouthpieces.
