The F107B RS Berkeley Open Hole Flute is the step-up instrument for advancing flutists ready to transition to the French open-hole key system and extended range of the B foot joint. A custom silver-plated headjoint, drawn tone holes, stainless steel springs, and a split E/gizmo key provide the technical features that support developing tone, vibrato, and flexibility. This is the ideal instrument for Intermediate players preparing for advanced repertoire and auditions.
