Reference Notes
Symphonic-style throat variant with standard #24 backbore from the Bach Symphonic family. Includes Bach 3C 24 coverage. 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.
