America's #1 flute specialty house since 1983.
The Valgon acoustical bass flute ring provides an additional source of resonance. Place on either head joint or foot joint, or both. Using considerably less effort, players will immediatlely notice an improvement in all aspects of their playing. The Valgon Rings (TM) control and stabilize the oscillating air column on the outside of your instrument, resulting in reduced turbulence inside the bore. The bass flute rings are sold individually.
