Reference Notes
CB0 cup on a bass trombone shank — 31.2mm outer rim (44.8mm OD), 8.0mm throat. Contrabass cup geometry adapted for bass trombone players seeking extreme low-register depth. Use these measurements as a comparison starting point: fit and response still depend on the player, dental structure, instrument receiver, and each manufacturer's measuring method.
