Reference Notes
The Giddings 7 GW Helios is a medium-cup Bb trumpet mouthpiece featuring a 16.35mm rim diameter and 3.66mm throat and 27 drill. It has a standard shank, stainless-steel construction. Well-suited for classical, commercial and student/developing playing. 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.
