The F series flugelhorn mouthpieces follow the same philosophy as our trumpet mouthpieces and are available in three cup depths and three diameters. They are precisely matched to our Giolo and JooJazz flugelhorns and ensure optimum intonation across all registers. Depending on the cup depth, the sound ranges from warm and dark to clear and focused, allowing the F series to adapt flexibly to different musical requirements. A quick response and stable tone formation ensure high precision and good control.
