I would think that these items would work together like a hand in a glove, but the lig is barely large enough to fit on the mouthpiece when there is a reed in place. It is difficult to adjust the reed, because even when loosened as much as possible, the ligature is fairly tight. I attribute the problem to the mouthpiece, as no other lig that I have (admittedly not a wide selection) will even fit on the SL3. What is puzzling is that Vandoren's matching lig is such a poor fit. Is it just me, or has anyone else had this experience? For those with SL3 pieces, what lig do you use?
