Powell Sonar flutes offer a range of instruments which allow flutists to perform at professional levels at affordable prices. The Powell Sonar flute retains some of the handmade instrument components that are critical for acoustical quality from the Verne Q. Powell Signature flute. Thus, Powell Sonar flutes feature bodies made at Powell Flutes using the new patented Zinki technology and handmade Powell Signature headjoints. Both the body and the headjoint are made at Powell's Massachusetts workshop. Every Sonar instrument goes through a strict quality inspection and adjustment process by world class Sonar technicians.
