Large Bore Trombone: Brass Rim

Pickett Brass Large Bore Trombone Brass Rim

Choose the diameter and rim profile that feel right for your playing, then pair your rim with a matching Pickett large-bore underpart. This brass rim is the contact surface of your modular mouthpiece, allowing you to retain a familiar rim while exploring different cup depths or underpart weights.

Match the rim number to the cup number. Pickett large-bore brass and acrylic rims fit both standard-weight and lightweight large-bore underparts of the same numbered size. For example, pair a size 5 rim with a size 5 underpart, then choose the cup depth you prefer.
