The A4, developed with Amik Guerra, is the lightweight version of the popular A4 with modern design. It combines the free response and big concentrated sound of the A4 with weight saving specifications. A lighter mouthpiece receiver is accompanied by lighter braces and a lighter valve section. Also the instrument has a smaller bell with French bead, 126 mm compared to the 140 mm of the A4. The instrument plays very lively and feels very open while playing, giving the player a confident feeling.
