This is a set of two ligatures for Harrison alto saxophones. This set includes one in pink gold and one in gold plate, both A2 (for Selmer S80 and S90 rubber mouthpieces). The gold plate ligature is an A2F (Forte IR model), which has a thicker metal construction than the standard model, resulting in a more profound tone. This model allows you to experience different sounds by combining three different thickness parts to the ligature screw. Both ligatures were test-played at a wind instrument specialty store and then stored at home. They were purchased as spares, but I am selling them because I will not be using them. Thank you. *Instant purchase is welcome.*
