Reference Notes
Bach Megatone 1½C appears in the Trumpet catalog section with 17 mm rim, Medium cup, 3.73 mm throat, #10 backbore, and standard shank. Database tags list it for Orchestral, Classical, and All Around use. Noted features include Heavyweight, Megatone, and Improved Slotting. 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.
