Common Questions About the William S. Haynes AF680SE-BO
How does the AF680 compare with the Amadeus AF580 and AF780?
The AF680 uses a solid silver Haynes headjoint with a silver-plated body and mechanism. The AF580 uses a silver-plated headjoint with a solid silver lip plate and riser, while the AF780 adds a solid silver body and footjoint.
What does the split E mechanism contribute?
A split E mechanism improves the response and stability of the third-octave E by closing an additional G key vent when that note is fingered. It is especially useful in advanced repertoire requiring secure upper-register articulation.
What is the significance of the Haynes A=442 scale?
The Haynes A=442 scale is designed around a pitch standard commonly encountered in modern orchestral and conservatory settings. It gives the player an appropriate tuning foundation while retaining normal headjoint adjustment for ensemble conditions.
