YamahaProfessional 677H Series Flute Offset G C# Trill Key Split E, Gizmo Key
Independent shopping perspective
The Korena take
Yamaha’s professional 677H combines a sterling-silver headjoint and body with nickel-silver keys. The hand-finished, modified Type A headjoint is described as responsive with a broad dynamic range, while acoustic annealing is applied to the headjoint, body, and footjoint for even response across registers. Its 0.43mm wall thickness and hand-finished headjoint are presented for a warm, rich tone. Straubinger Phoenix Pads provide a more precise, consistent seal and are designed for lighter touch and quicker action.
