Condition & Setup
This lightly used model is in excellent playing order and has been professionally serviced, set up, and play-tested. The sterling silver surfaces and silver-plated keywork are well preserved overall, with a few faint hairline handling marks near the headjoint embouchure area.
Who the Amadeus AF780-BO Concert Flute Is For
The AF780-BO is well suited to advancing students, college flutists, adult players, teachers, and doublers who want an upper-level intermediate flute with solid-silver construction and the Haynes A=442 scale. Solid silver is commonly chosen for its breadth of tonal color, while the French-style mechanism supports developed technique and the offset G provides a familiar left-hand position. Players seeking a handmade Haynes Q Series or Custom instrument should view the AF780 as a different category: a high-specification Amadeus flute intended for serious study and performance.
Common Questions About the Haynes Amadeus AF780-BO
How does the AF780 differ from the Amadeus AF680?
The AF680 pairs a solid-silver headjoint with a silver-plated body and mechanism. The AF780 adds a solid-silver body and footjoint while retaining a silver-plated mechanism, placing it above the AF680 within the Amadeus concert flute line.
What do the offset G and B footjoint contribute?
The offset G places the left-hand G keys in a position many flutists find natural. The B footjoint extends the instrument's range to low B and adds the longer footjoint configuration commonly used on advanced concert flutes.
How does solid-silver construction affect the flute?
Solid-silver tubing is commonly associated with a broad tonal palette, nuanced dynamic response, and greater color as the player develops. Headjoint choice, embouchure, and air use remain central to the final sound and response.
