The Armstrong headjoint offers players crisp response and ease of playing throughout all registers. The offset G key follows the natural contour of student's hands and makes playing more comfortable. Armstrong's signature CNC key cups ensure that pads will seat perfectly flat which prevents air leaks. Top adjusting screws provide ease of repair and adjustment to keys on the 102. Bottom adjusting screws provide a sleeker, more professional look on the 104. Built in Elkhart, Indiana, the Armstrong flute is designed to last and provide a superb playing experience for students.
